NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram of a car moving on a banked road. The forces acting on the car include gravitational force (mg), normal force (N), and frictional force (f). If the car is at maximum speed without skidding, which equation correctly represents the vertical forces in equilibrium?
A
N cos θ = mg + f sin θ
B
N sin θ = mg - f cos θ
C
N = mg + f cos θ
D
N cos θ = mg - f sin θ
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, Eq. (4.20a) describes the vertical forces in equilibrium on a banked road, where N cos θ = mg + s Nμ sin θ. The option A reflects this equation.
