A hollow ball with radius R = 2 cm has a charge of -2 nC spread uniformly over its surface (see the figure). The center of the ball is at P1 = cm. A point charge of 3 nC is located at P3 = cm. (The diagram below is not drawn exactly to scale.) P2 X PIX Part 1 Your answer is partially correct. What is the net electric field at location P2 = cm? E = N/C Save for Later Attempts: 1 of 10 used Submit Answer Part 2 Your answer is partially correct. At a particular instant an electron is at location P2. What is the net electric force on the electron at that instant? F =
