NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a block on a rough horizontal surface. The block is subjected to a horizontal force F and moves with a constant velocity. Which of the following correctly represents the relationship between the frictional force f and the applied force F?
A
f = F
B
f > F
C
f < F
D
f = 0
Correct Answer
Option A
Detailed Explanation
When the block moves with constant velocity, the net force on it is zero. Thus, the frictional force must be equal to the applied force to maintain equilibrium, as per the conditions of constant motion.
