A stationary body of mass 3 kg explodes ...

A stationary body of mass `3 kg` explodes into three equal pieces. Two of the pieces fly off at right angles to each other. One with a velocity of `2hati m//s` and the other withl velocity of `3hati m//s`. If the explosion takes place in `10^(-5)` the average force acting on the third piece in newtons
