Figure below shows a body of mass `M` moving with the uniform speed on a circular path of radius, `R`. What is the change in acceleration in going from `P_(1)` to `P_(2)`

Options

A. Zero
B. `v^(2)//2R`
C. `2v^(2)//R`
D. `(v^(2))/(R) xx sqrt2`

Answer

D

Explanation

`Delta a= 2a sin ((theta)/(2))=2a xx sin 45^(@)= sqrt2a= sqrt2 (v^(2))/(R)`
