PHY 101 Circular Motion Objective Question

Question

The formula for the optimum banking angle (θ) for a car moving with speed v on a curve of radius r is:
Options
A tan θ = gr / v²
B sin θ = v² / gr
C tan θ = v² / gr
Correct Answer
D cos θ = v² / gr
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture provides the formula for the optimal banking angle when the frictional force is zero as tan θ = v²/(gr).

Hint

This formula is derived by balancing force components and canceling out mass.
