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 P, = cm. A point charge of 6 nC is located at Py = cm. (The diagram below is not drawn exactly to scale.) P2 X PX P3 . What is the net electric field at location Py = cm? N/C At a particular instant an electron is at location Py. What is the net electric force on the electron at that instant? F = What is the direction of the net electric force on the electron? O The force is opposite to the direction of the net electric field at P2 O There is not enough information to determine the direction of the force O The force is in the same direction as the electric field at P2 The force is at right angles to the direction of the electric field at P2
