Two particles A and B seperated 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 = (72V^(2))/(25piR)` Then A collides B after certain

Options

A. The time lapse for the two bodies collideis `(6piR)/(5V)`
B. The angle covered by A is `(11pi)/(6)`
C. Angular velcity of A is `(11V)/(R)`
D. The radial accelrations of A is `(289V^(2))/(5R)`

Answer

B
