Two small balls having the same mass and charge and located on the same vertical at heights h_(1) and h_(2) are thrown in the same direction along the horizontal at the same velocity v. The first ball touches the ground at a horizontal distance R from the initial vertical position. At what height h_(2) will the second ball be at this instant? Neglect any frictional resistance of air and the effect of any induced charge on the ground.

The first vall touches the ground at a horizontal distance R from the initial vertical position. At waht heigth h_(2) will the second ball be at this instant? Neglect any frictional resistance of air and the effect of any induced charge on the ground.

From the top of the tower, a ball A is dropped and another ball B is thrown horizontally at the same time. Which ball strikes the ground first ?

Two projectiles thrown from the same point at angles 60^@ and 30^@ with the horizontal attain the same height . The ratio of their initial velocities is

Two particale of same mass and charge throw in same direction along the horizonal with same velocity v from two didffent heights h_(1) and h_(2) (h_(1)lth_(2)). Initially they were located in the same vertical line. Select the corredct alternative (s).
