4. 5. What is the total charge of 1 gram of electrons? An alpha particle (2 protons, 2 neutrons) is placed between two stationary, charged objects as shown. It is 0.0030 m to the right of the object carrying a +1.0 x 10-2 C charge and 0.0020 m to the left of the object carrying a -2.0 x 10-2 C charge, as shown below. 0.0030 m 0.0020 m +1.0 x 10- C -2.0 x 10- C a) What is the net magnitude and direction of the electrical force acting on the a particle? b) At what rate and in what direction will the a particle accelerate?
