The force F1 passes through the axis of rotation, so it will not produce a torque.
The force F2 is perpendicular to axis and radius, so it will provide a torque = r*F2 about the axis of rotation, where ‘r’ is the distance of point of application of force F2 from the axis of rotation.
Therefore, torque = r* F2= 0.05 * 5 Nm
= 0.25Nm.
The force F2 is perpendicular to axis and radius, so it will provide a torque = r*F2 about the axis of rotation, where ‘r’ is the distance of point of application of force F2 from the axis of rotation.
Therefore, torque = r* F2= 0.05 * 5 Nm
= 0.25Nm.

To find the net torque on the body, we need to calculate the torque produced by each force and then add them together.
The torque produced by a force is given by the formula:
τ = r x F
where τ is the torque, r is the radius vector from the axis of rotation to the point of application of the force, and F is the force vector.
For Force F1, since its vector passes through the axis of rotation, the radius vector r is zero. Therefore, the torque produced by F1 is zero.
For Force F2, since it is perpendicular to the axis of rotation and at a point 5cm from the axis, the radius vector r is 5cm. The torque produced by F2 is:
τ2 = r x F2
Since F2 is perpendicular to the radius vector, the cross product of r and F2 is the product of their magnitudes:
τ2 = 5cm * 10N
Converting cm to meters:
τ2 = 0.05m * 10N
τ2 = 0.5Nm
Therefore, the net torque on the body is 0.5Nm.
The torque produced by a force is given by the formula:
τ = r x F
where τ is the torque, r is the radius vector from the axis of rotation to the point of application of the force, and F is the force vector.
For Force F1, since its vector passes through the axis of rotation, the radius vector r is zero. Therefore, the torque produced by F1 is zero.
For Force F2, since it is perpendicular to the axis of rotation and at a point 5cm from the axis, the radius vector r is 5cm. The torque produced by F2 is:
τ2 = r x F2
Since F2 is perpendicular to the radius vector, the cross product of r and F2 is the product of their magnitudes:
τ2 = 5cm * 10N
Converting cm to meters:
τ2 = 0.05m * 10N
τ2 = 0.5Nm
Therefore, the net torque on the body is 0.5Nm.
