Question
A bomb of mass M @ rest explodes into 2 fragments of masses m1 &m2 . The total energy released in the explosn is E if E1 &E2 represent the energies carried by m1 &m2. then which of the followg is correct
a) E1=(m2/M)E
B) E1= m1/m2 E
C) E1= m1/M E
D) E1= m2/m1 E
Joshi sir comment
(1) is correct
the ratio of energy will be E1/E2 = m2/m1
