Question 8 1 pts The dashed lines in the diagram represent cross sections of equipotential surfaces drawn in 1 V increments. 2 V 1V B OV -1 V •C -2 V -3V What is the work done by the electric force to move a +1C charge from A to B? Express your answer in Joules

Question 9 1 pts The dashed lines in the diagram represent cross sections of equipotential surfaces drawn in 1V increments. 2 V 1 V B OV -1 V • C -2 V -3V What is the work done by the electric force to move a -1 charge from A to D? Express your answer in joules.

Question 10 1 pts How much work does the electric force do in moving a -7.4 C charge from ground to a point whose potential is +50 V higher? (answer in joules to 2 significant figures in scientific notation, where is written as 1.2E-6)
