Question : A particle moves along a circle of radius (20 𝜋 ) m with constant tangential acceleration. If the velocity of the particle is 80 ms −1 , at the end of seconds revolution after motion has begun, the tangential acceleration is

(A) $40ms^{-2}$

(B) $640ms^{-2}$

(D) $40ms^{-2}$

Answer : option (A)

Solution :

A particle moves along a circle of radius (20 𝜋 ) m with constant tangential acceleration. If the velocity of the particle is 80 ms −1 , at the end of seconds revolution after motion has begun, the tangential acceleration is
