Several spherical drops of a liquid of density 'd' and radius 'r' coal

1.	Several spherical drops of a liquid of density 'd' and radius 'r' coalesec to form a single drop of radius 'R'. If all the energy released is converted into K.E. Then the velocity acquired by the drop is
Answer» `sqrt((6T)/(d)((1)/(R)-(1)/(R)))` `sqrt((3T)/(d)((1)/(r)-(1)/(R)))` `sqrt((T)/(6d)((1)/(r)-(1)/(R)))` `sqrt((T)/(3d)((1)/(r)-(1)/(R)))` ANSWER :A
