A particle is moving on a circle of radius

R

such that at every instant the tangential and radial accelerations are equal in magnitude. If the velocity of the particle be

{v}_0

{t}=0

, the time for the completion of half of first revolution will be

View answer and explanation

Correct option: B

\frac{R}{v_0}\left(1-e^{-\pi}\right)

Option B (

\frac{R}{v_0}(1-e^{-\pi})

) is correct because it represents the time for half a revolution when tangential and radial accelerations are equal.
