NEET Physics Friction MCQ Question
Type: MCQ-numerical-Medium-Class 11
A block of mass 5 kg is placed on a horizontal surface. The maximum static frictional force between the block and the surface is 30 N. What is the coefficient of static friction?
A
0.6
B
0.5
C
0.4
D
0.3
Correct Answer
Option A
Detailed Explanation
The maximum static frictional force is given by f_s = μ_s * N where N = mg. Here, N = 5 * 9.8 = 49 N. Solving 30 = μ_s * 49 gives μ_s = 0.6.
