1.	A stationary body of mass 3 kg explodes into three equal pieces. Two of the pieces fly off in two mutually perpendicular directions, one with a velocityof 3hati" m s"^(-1). And the other with a velocity of 4hatj" m s"^(-1). If the explosion occurs in 10^(-4)" s", the average force acting on the third piece in newton is
Answer» `(3HATI + 4haj)XX 10^-4` `(3hati - 4haj)xx 10^-4` `(3hai + 4hatj)xx 10^-4` `(3hati + 4hatj ) xx 10^4)` ANSWER :`-(3hati + 4 HATJ) xx 10^4`
