If 'U' be the speed of projection and V_(1) be thevelocity of striking the inclined plane when projected such that range up the plane is maximum. And V_(2) be the velocity of striking the plane when projected such that range down the plane is maximum then

If 'U' be the speed of projection and V_(1) be thevelocity of striking

1.	If 'U' be the speed of projection and V_(1) be thevelocity of striking the inclined plane when projected such that range up the plane is maximum. And V_(2) be the velocity of striking the plane when projected such that range down the plane is maximum then
Answer» `U^(2)=V_(1)V_(2)` `V_(1)^(2)=UV_(2)` `V_(1)V_(2)` are PERPENDICULAR to their initial VELOCITIES `V_(1)` may be GREATER than `V_(2)` ANSWER :A::C
