Two particles `A` and `B` separated by a distance `2R` are moving counter clockwise along the same circular path of radius `R` each with uniform speed `v`. At time `t=0`, `A` is given a tangential acceleration of magnitude `a = (32v^(2))/(25piR)` in the same direction of initial velocity

Options

A. The time - lapse for the two bodies to collide is `(6piR)/(5V)`
B. The angle covered by (A) is `(9pi)/4`
C. Angular velocity of A is `(11V)/(5R)`
D. Radial acceleration of A is `(289V^2)/(5R)`

Answer

B
