    Electric force of Van de Graaff generator problem.

    A Van de Graaff generator is charged so that a proton at its surface accelerates radially outward at 1.45 10^12 m/s2. Find the following. (a) the magnitude of the electric force on the proton at that instant magnitude (b) the magnitude and direction of the electric field at the surface of...
