Aprojectile is projected with (3 hat(i) + 4 hat(j)+5 hat(k))ms^(-1). Point of projection is taken as origin and East, North , vertically upward directions are taken as positive x, y, z-directions respectively. (g=10ms^(-2)) All the units are in SI system Its displacement when it hits the XY-plane is :

1.	Aprojectile is projected with (3 hat(i) + 4 hat(j)+5 hat(k))ms^(-1). Point of projection is taken as origin and East, North , vertically upward directions are taken as positive x, y, z-directions respectively. (g=10ms^(-2)) All the units are in SI system Its displacement when it hits the XY-plane is :
Answer» `( 3 hat(i) + 4 hat(J))/(5)` `(3 hat(i) + 4 hat(j))/(2)` `3 hat(i)+4 hat(j)` `6 hat(i) + 4 hat(j)` Answer :C
