An isolated particle of mass m is moving in a horizontal (x – y) plane along the x-axis, at a certain height above the ground. It suddenly explodes into two fragments of masses 
& 
. An instant later, the smaller fragment is at y = +15 cm. The larger fragment at this instant is at –
Text Solution
Verified by ExpertsThe correct answer is:
A
y CM = 0
y CM = 
+ 
y 1 = + 15 ∴ y 2 = –5 cm
