An isolated particle of mass m is moving in a horizontal plane (x-y), along the x-axis, at a certain height above the ground. It suddenly explodes into two fragments of masses m/4 and 3m/4. An instant later, the smaller fragment is at

y = + 15

cm. The larger fragment at the instant is at

View answer and explanation

Correct option: A

y = - 5\,cm

Option A (

y = - 5\,cm

) is correct because the center of mass remains unchanged after the explosion, allowing us to calculate the position of the larger fragment.
