A shell at rest on a smootyh horizontal ...

A shell at rest on a smootyh horizontal surface explodes into two fragments of masses `m_(1)` and `m_(2)`. If just after explosion, `m_(1)` move with speed u, then work done by internal forces during explosion is :-

A

`(1)/(2)(m_(1)+m_(2))(m_(2))/(m_(1))u^(2)`

B

`(1)/(2)(m_(1)+m_(2))u^(2)`

C

`(1)/(2)m_(1)u^(2)(1+(m_(1))/(m_(2)))`

D

`(1)/(2)(m_(2)-m_(1))u^(2)`
