Two small spheres having same mass and charge are loacated at the same vertical line at heights h1 and h2(h2>h1). They both are thrown simultaneously with the same velocity V in the same direction along the horizontal. From the initial vertical line, the first sphere hits the ground ata distance l. Then at this instance height of second ball.
