Physics

Two point charges, Q1 = 3.3?C and Q2= -1.5?C ,are placed on the x axis. Suppose thatQ2 is placed at the origin, and Q1 is placed atthe coordinatex1 = ? 6.0cm (Figure 1) .

Part A:

At what point(s) along the x axis is the electric fieldzero? Determine the x-coordinate(s) of the point(s).

Express your answer using two significant figures. If there ismore than one answer, enter your answers in ascending orderseparated by commas.

Part B:

At what point(s) along the x axis is the potentialzero? Determine the x-coordinate(s) of the point(s).

Express your answer using two significant figures. If there ismore than one answer, enter your answers in ascending orderseparated by commas.
