NEET Physics Friction MCQ Question
Type: MCQ-numerical-Hard-Class 11
A block of mass 10 kg is at rest on a horizontal surface with a coefficient of static friction μs = 0.4. What is the maximum horizontal force that can be applied to the block without causing it to move?
A
39.2 N
B
40.0 N
C
0 N
D
98.0 N
Correct Answer
Option A
Detailed Explanation
The maximum static friction force is given by fs ≤ μs N, where N = mg. Here, N = 10 kg × 9.8 m/s² = 98 N, so fs ≤ 0.4 × 98 N = 39.2 N.
