Six negative point charges and two positive point charges are arranged in a circle as shown in the figure. The charges have equal magnitude. The magnitude of the electric potential generated by each charge is 120 V at the origin. What is the net electric potential generated by all the charges at the origin O? 90 y -Q Fig. A Answer: Net potential Answer: Net potential Volts Volts

There Is a positive charge Q at x = 5 cm on the x-axis, and a negative charge -2Q at x = 15 cm on the x-axis. What are the total electric field and electric potential at x = 10 cm on the x- axis? Assume the usual convention for defining the potential of a polnt charge. E (vector) points to positive x, V is negative E (yector) points to positive x, V is positive E (vector) points to negative x, V is negative E (vector) is zero, V is zero E (vector) is zero, V snegative E (vector) points to negative Vis postive

Three point charges, Q1 = 12.4 uC, Q2 = -30.6 uC, and Q3 = 87.3 uC, are arranged on the corners of a square of side length 70.1 cm, as shown in the figure. Calculate the electric potential V at point A
