Three charges are at the corners of an isosceles triangle as shown in the figure (Figure 1). The 5.00 C charges form a dipole.

Three charges are at the corners of an isosceles triangle as shown in the figure (Figure 1). The ±5.00μC charges form a dipole.

A. Find the magnitude of the force the -10.00μC charge exerts on the dipole.

B. Find the direction of the force the -10.00μC charge exerts on the dipole.(Suppose that y-axis directs to the top of the image.)

C. For an axis perpendicular to the line connecting the ±5.00μC charges at the midpoint of this line, find the torque (magnitude) exerted on the dipole by the -10.00μC charge.

D. Find the direction of the torque.
