- a)Tangential
- b)Perpendicular
- c)Parallel
- d)Normal
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
The frictional force developed always acts ____________ to the surface...
The friction is the phenomena that defines that there is a resistance which is present there between the two surfaces. This friction is applied tangentially to the surfaces in contact. Thus the main thing is that the forces on both of the surfaces act tangential to each other.

Frictional Force and its Direction
Frictional force is the force that opposes the relative motion between two surfaces in contact. It always acts along the surface of contact between the two surfaces. The direction of the frictional force depends on the orientation of the surfaces in contact.
Tangential Direction
When two surfaces are in contact and are moving relative to each other, the frictional force acts in the tangential direction to the surface of contact. This is because the relative motion between the surfaces causes the interlocking of the surface irregularities, which generates a force that opposes the motion.
Normal Direction
When two surfaces are in contact and are not moving relative to each other, the frictional force acts in the normal direction to the surface of contact. This is because the irregularities in the surface of the two objects interlock, generating a force that opposes the force trying to push the two objects together.
Paralle Direction
When two surfaces are in contact, but there is no relative motion between them and the force trying to push the two surfaces together is applied in a direction parallel to the surface of contact, the frictional force acts in the direction opposite to the applied force.
Conclusion
In conclusion, the frictional force always acts in the direction that opposes the relative motion or the force trying to push the two surfaces together. When the two surfaces are in contact and are moving relative to each other, the frictional force acts in the tangential direction to the surface of contact.

Tangential Direction
When two surfaces are in contact and are moving relative to each other, the frictional force acts in the tangential direction to the surface of contact. This is because the relative motion between the surfaces causes the interlocking of the surface irregularities, which generates a force that opposes the motion.
Normal Direction
When two surfaces are in contact and are not moving relative to each other, the frictional force acts in the normal direction to the surface of contact. This is because the irregularities in the surface of the two objects interlock, generating a force that opposes the force trying to push the two objects together.
Paralle Direction
When two surfaces are in contact, but there is no relative motion between them and the force trying to push the two surfaces together is applied in a direction parallel to the surface of contact, the frictional force acts in the direction opposite to the applied force.
Conclusion
In conclusion, the frictional force always acts in the direction that opposes the relative motion or the force trying to push the two surfaces together.
