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:

Answer:

Solution:

As it is rolling

$\Rightarrow ω = \frac{V}{R}$

$V_{Q} = 0$

$\Rightarrow V_{P / Q} = ω (2 R) = 2 V$

$\Rightarrow a_{P / Q} = \frac{V_{P / Q}^{2}}{2 R} = \frac{{(2 V)}^{2}}{2 R} = \frac{2 V^{2}}{R}$
