Answer Key : (a) -

(a)

L  is the energy of explosion, then since it is just sufficient to carry the bullet to a height  so

We have  Now, if  and  are the respective velocities of the bullet and the gun, respectively, then, from the law of conservation of linear momentum,

( i )

Also, 

 [from Eq. (i)]
