An initially stationary device lying on a frictionless floor explodes

1.	An initially stationary device lying on a frictionless floor explodes into two pieces and slides across the floor. One piece is moving in positive x-direction then other piece is moving inA. positive y- directionB. negative y-directionC. negative x-directionD. at angle from x-direction
Answer» Correct Answer - C ( c) From law of conservation of momentum, `p_(i)=p_(f)` and initial momentum, `p_(i)=mu=m(0)=0` `therefore p_(f)` should also be zero. Hence, other piece will move in negative x-direction.
