A wheel of radius R rolls on the ground with a uniform velocity v . The relative acceleration of topmost point of the wheel with respect to the bottom most point is

Options

  1. Av ² R
  2. B2 v ² R
  3. Cv ² 2 R
  4. D4 v ² R

Correct answer

B. 2 v ² R

Step-by-step solution

As a_ CM =0 [ v _ CM = . constant ] , Tangential acceleration of each point | a _ AB |= 2 v ² R
