- If the metal sphere on the Van de Graff has a charge of 0.14 Coulombs and the person has a mass of 62 kg, how much excess charge would the person need in order to levitate at a distance 25 cm from the center of the charged metal sphere if there is a distance 25 cm from the person to the sphere using Coulomb's Law to calculate the electrical force. Give your answer as the number of Coulombs (with no unit label, as usual).arrow_forwardA balloon is rubbed on a sweater, giving the balloon a negative charge by adding an extra 3.9 x 107 electrons compared to its neutral state.
