16. A charge of -5.00 C is separated from another charge of -2.00 C by a distance of 1.20 m. Calculate a) The net electric field midway between the two charges [7.49 x 1010 N/C [toward the -5.00 C charge]] b) The position where the net electric field is zero. [0.735 m from the -5.00 C charge] 17. Find the net electric field intensity at point C in the diagram below. [1.2 x 107 N/C [90.09]] 0.040 m +20 uC +2.0 UC 0.060 m 18. If an alpha particle experiences an electric force of 0.250 N at a point in space, what electric force would a proton experience at the same point? [0.125 N] 19. What is the initial acceleration on an alpha particle when it is placed at a point in space where the electric field strength is 7.60 x 104 N/C? [3.66 x 1012 m/s?] 20.

A proton is placed in an electric field produced by another larger charge. If the magnitude of the field at this position is 1.00 x 105 N/C, calculate the magnitude of the electrostatic force on the proton. [1.6 x 10-16 N] 15. An electron and a proton are 5.29 x 10-17 m apart in a hydrogen atom. Determine the net electric field at a point midway between the two charges. [4.11 x 1012 N/C] [towards the electron]3. Two neutral metal spheres on wood stands are touching. A negatively charged rod is held directly above the top of the left sphere, not quite touching it. While the rod is there, the right sphere is moved so that the spheres no longer touch. Then the rod is withdrawn. Afterward, what is the charge state of each sphere? Use charge diagrams to explain your answer. 4. Two identical metal spheres have different charges. One has a charge of +10 C and the other has a charge of -20 C. If the spheres are allowed to touch each other for a time and then are moved away from each other, what is the final charge on each sphere? Explain 5. A 1.8 g (0.0018 kg) pith ball is suspended from a thread and placed in an Charged rod electric field. When placed in the electric field, the pith ball is deflected to the left so that the thread makes a 9.50 angle with the vertical. Calculate the electrostatic force on the pith ball. (0.0030 N)
