A wheel of radius R rolls on the ground with a uniform velocity v . The relative acceleration of the topmost point of the wheel with respect to the bottommost point is
Options
- Av 2 R
- B2 v 2 R
- Cv 2 2 R
- D4 v 2 R
Correct answer
B. 2 v 2 R
Step-by-step solution
As it is rolling ⇒ ω = V R V Q = 0 ⇒ V P / Q = ω ( 2 R ) = 2 V ⇒ a P / Q = V P / Q 2 2 R = ( 2 V ) 2 2 R = 2 V 2 R
