At t = 0 a projectile is fired from a point O(taken as origin) on the ground with a speed of 50 m/s at an angle of 53° with the horizontal. It just passes two points A & B each at height 75 m above horizontal as shown.Q.6 The horizontal separation between the points A and B is(A) 30 m(B) 60 m(C) 90 m(D) None Q.7 The distance (in metres) of the particle from origin at t = 2 sec. (A)60√2(B) 100(C) 60(D) 120
