    article Is uncharged and is thrown vertically upward from 1 with a speed of 25.0 m/s. As a result, it attains a height h. The particle is then given a positive charge and reaches the same maximum height h when thrown verti- ly upward with a speed of 30.0 m/s. The electric potential at height h exceeds the electric potential at ground level. Finally he particle is given a negative charge-q. Ignoring air resistance determine the speed with which the...
