If a wheel of radius r turns through an angle of 30o then the distance through which any point on its rim moves is
Correct answer: B. π/6×r
- A. π/3×r
- B. π/6×r
- C. π/30×r
- D. π/180×r
Explanation
Arc length = Distance moved by point= 30/360 *2 πr = 1/6 πr

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
