question_answer
A wheel of radius R rolls without slipping 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
A)\[\frac{{{v}^{2}}}{R}\]
B) \[\frac{2{{v}^{2}}}{R}\]
C)\[\frac{{{v}^{2}}}{2R}\]
D) \[\frac{4{{v}^{2}}}{R}\]
Correct Answer:
B
Solution :
[b] Acceleration w.r.t. centre of wheel are shown, the relative acceleration \[=\frac{2{{v}^{2}}}{R}\]
