A cart is sliding on a smooth incline An observer `(O_(1))` is fixed to cart and another abserver fixed on ground `(O_(2))` observes a loose bolt that is released from ceiling at the instant of release cart has velocity `v_(0)` as seen by `O_(2)` Mark the correct option A. Trajectory of bolt for `O_(1)` is parabolaB. Trajectory of bolt for `O_(2)` is straight line inclined at an angle 0with verticleC. Trajectory of bolt for `O_(2)` is a straight line perpendicular to ceiling of cart.D. Trajectory of bolt for `O_(1)` is straight line

Answer» Correct Answer - D
for observer on cart
` vec(v)_(rel)=0`
` vec(s) _(rel)=1/2vec(a)_(rel)t^(2)`
Trajectory is straight line along `vec(a)_(rel)` for observer on ground trajectory is parabola because `vec(v) _(0)and vec(g)` are at angle `theta` initially
