Toward the bottom of the page e./Out of the page f./Into the page B 2. If the total charge on the insulating rod in #4 contains -35.2 uC of charge. How many more electrons than protons does the rod contain? 3. Two positive point charges Q and 30 are separated by a distance R. If the charge Q experiences a force of magnitude Fwhen the separation is R, what is the magnitude of the force on the when the separation is increased to 4? a. F/16 b. F /8 C. F/4 d. 4F e. 16F 4. Three charges are located along the x axis as shown in the drawing. Determine the magnitude and direction of the Net Force of the -9 UC change. 3 LIC -1 UC 10 12 (m) Magnitude
