Marks: +1, -0

Paiticle A is moving with a constant velocity of VA = 50 ms−1 in positive x direction. It crossed the origin at time t = I Os . Another particle B started at t = 0 from the origin and moved with a uniform acceleration of aB = 2 ms−1 inpositive x direction. Then the time for which was A ahead of B during the subsequent journey is 10 √n then the value of n is
