NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a diagram where a block is placed on a rough inclined plane making an angle θ with the horizontal. The block is in equilibrium due to the forces acting on it. Which equation correctly describes the equilibrium condition in terms of normal force N and static friction coefficient μs?
A
N cos θ = mg + μs N sin θ
B
N sin θ = mg + μs N cos θ
C
N = mg cos θ + μs mg sin θ
D
N = μs mg cos θ - mg sin θ
Correct Answer
Option A
Detailed Explanation
Option A is correct as it reflects the equilibrium condition derived from the components of forces acting on the block, where N cos θ balances mg and frictional force.
