A ball of mass 1.6kg is projected with a velocity of 20m/s at an angle of 37º above the horizontal. After 1.2sec., gravitational field vanishes and a force of constant magnitude is applied after that, force being always perpendicular to the direction of motion till it strikes the ground. When it strikes the ground it is moving vertically. Choose the correct option (g = 10m/s2) :
(A) Initially path is parabolic and later on it becomes hyperbolic
(B) The radius of the circle will be 7.2m and constant magnitude of force applied is 512/9N
(C) The speed during circular motion will be 16 m/s
(D)The time it takes to strike the ground is less than that it would have taken in projectile motion
