1.	The object at rest suddenly explodes into three parts with the mass ratio 2:1:1.The parts of equal masses move at right angles to each other with equal speed 'v'. the speed of the third part after explosion will be
Answer» V `SQRT2V` `(v)/(2)` `(v)/(sqrt2)` SOLUTION :`m u=m_(1)v_(1)+m_(2)v_(2)+m_(3)v_(3)`
