Which figure correctly represents the direction of the frictional force between the ball and the inclined plane?
Correct Answer: A
Solution :
Friction is the resistive force that arises when two bodies or surfaces move in contact with each other. Since it is a resistive force, it opposes the motion of a body. Hence, the direction of the frictional force on the ball is opposite to its direction of motion. This is correctly represented in the figure given in alternative A. The correct answer is A.
