In case of projectle motion if two projectles A and B are projected with same speed at angles `15^(@)` and `75^(@)` respectively to the horizontal then:

Two particle are projected with same initial velocities at an angle 30^(@) and 60^(@) with the horizontal .Then

Two particle are projected with same initial velocities at an angle 30^(@) and 60^(@) with the horizontal .Then

Two bodies of same mass are projected with the same velocity at an angle 30^(@) and 60^(@) respectively.The ration of their horizontal ranges will be

Two bodies of same mass are projected with the same velocity at an angle 30^(@) and 60^(@) respectively.The ration of their horizontal ranges will be

If four balls A,B,C,D are projected with same speed at angles of 15^(@),30^(@),45^(@) and 60^(@) with the horizontal respectively, the two balls which will fall at the same place will be-

On an inclined plane two particles A and B are projected with same speed at the same angle with the horizontal, particle A down and particle B up the plane. If the ratio of time of flight of A and B is cot theta , where theta is the angle at which B is projected measured from inclined plane, find the angle at which particles are projected.
