A Van de Graaff generator has a 0.15 mC charge on its conducting spherical terminal. 50% Part (a) What is the magnitude of the electric field 2.8 m from the center of the terminal of the Van de Graaff generator? Since that distance is greater than the radius of the terminal, the field is the same as that due to the same charge concentrated at the center. Give your answer in newtons per coulomb.
