Question 1. Two charges of 1.0pC and -2.0p are 0.50 m apart at two vertices of an equilateral triangle as in Figure 1. a) What is the electric potential due to 1.0 0 charge at the third vertex, point P? b) What is the electric potential due to the -2.0pC charge at P? c) Find the total electric potential at P. d) What is the work required to move a 3.0pC charge from infinity to P?
