If a mass of 3kg carrying a charge of 0.115 Coulombs is launched upwards with an initial velocity of 6 metres per second in a uniform electric field, also directed vertically upwards, of strength E = 100 Newtons per Coulomb, what would be the maximum height reached by the mass in its subsequent motion.
Also, if the electric field was instead pointing in a direction at 52 degrees to the horizontal, what would be the maximum height reached in this case?
