(a) If velocity and acceleration are not in same direction, work done by force perpendicular to acceleration will not be zero.
(b) If the object is at rest no force can do work
(c) If force is perpendicular to velocity work done will be zero
(d) If the point on the body has velocity component in direction of application of force work done will be non-zero.
(b) If the object is at rest no force can do work
(c) If force is perpendicular to velocity work done will be zero
(d) If the point on the body has velocity component in direction of application of force work done will be non-zero.
The correct answers are: the object is at rest relative to ground but the point of application of force moves on the object, the force is always perpendicular to velocity of object

Work done by a force on an rigid object having no rotational motion wi...
Work done by a force on a rigid object with no rotational motion:
When a force is applied to a rigid object, the work done by the force can be determined by considering the displacement of the point of application of the force. In the case of a rigid object with no rotational motion, the work done by the force can be zero under certain conditions.
a) The force is always perpendicular to the acceleration of the object:
If the force applied to the object is always perpendicular to the acceleration of the object, then the work done by the force will be zero. This is because the angle between the force and the displacement is 90 degrees, and the work done is given by the equation W = F * d * cos(theta), where theta is the angle between the force and the displacement. Since cos(90) = 0, the work done will be zero.
b) The object is at rest relative to the ground, but the point of application of the force moves on the object:
In this scenario, although the object is not moving, the point of application of the force is moving. As a result, the displacement of the point of application of the force is non-zero. If the force is applied at different points on the object and the displacement of the point of application is perpendicular to the force, then the work done by the force will be zero. This is because the angle between the force and the displacement is 90 degrees, and cos(90) = 0.
c) The force is always perpendicular to the velocity of the object:
If the force applied to the object is always perpendicular to the velocity of the object, then the work done by the force will be zero. Similar to the previous cases, the angle between the force and the displacement is 90 degrees, and cos(90) = 0.
d) The point of application of the force is fixed relative to the ground, but the object moves:
In this case, as the object moves, the displacement of the point of application of the force is non-zero. If the force is applied at a fixed point on the object and the displacement of the point of application is perpendicular to the force, then the work done by the force will be zero. Again, this is because the angle between the force and the displacement is 90 degrees, and cos(90) = 0.
Therefore, the correct options are B and C, as in both cases the work done by the force on the rigid object with no rotational motion will be zero.
When a force is applied to a rigid object, the work done by the force can be determined by considering the displacement of the point of application of the force. In the case of a rigid object with no rotational motion, the work done by the force can be zero under certain conditions.
a) The force is always perpendicular to the acceleration of the object:
If the force applied to the object is always perpendicular to the acceleration of the object, then the work done by the force will be zero. This is because the angle between the force and the displacement is 90 degrees, and the work done is given by the equation W = F * d * cos(theta), where theta is the angle between the force and the displacement. Since cos(90) = 0, the work done will be zero.
b) The object is at rest relative to the ground, but the point of application of the force moves on the object:
In this scenario, although the object is not moving, the point of application of the force is moving. As a result, the displacement of the point of application of the force is non-zero. If the force is applied at different points on the object and the displacement of the point of application is perpendicular to the force, then the work done by the force will be zero. This is because the angle between the force and the displacement is 90 degrees, and cos(90) = 0.
c) The force is always perpendicular to the velocity of the object:
If the force applied to the object is always perpendicular to the velocity of the object, then the work done by the force will be zero. Similar to the previous cases, the angle between the force and the displacement is 90 degrees, and cos(90) = 0.
d) The point of application of the force is fixed relative to the ground, but the object moves:
In this case, as the object moves, the displacement of the point of application of the force is non-zero. If the force is applied at a fixed point on the object and the displacement of the point of application is perpendicular to the force, then the work done by the force will be zero. Again, this is because the angle between the force and the displacement is 90 degrees, and cos(90) = 0.
Therefore, the correct options are B and C, as in both cases the work done by the force on the rigid object with no rotational motion will be zero.
