The lines show equipotential contours in the plane of three point charges, Q 1 ,

Question

The lines show equipotential contours in the plane of three point charges, Q1, Q2, and Q3. The positions of the charges are marked by dots. The values of the potentials are in kilovolts as indicated, e.g., +5 kV, ?5 kV; the contour interval is 1 kV. The letters denote locations on the contours. For distances use the scale below the picture, to an appropriate accuracy. Select all the correct statements, e.g., AB.

A-Charge Q2 has the largest magnitude.

B-The electric field at i is stronger than at j.

C-The force on an electron at g points to the bottom of the page.

D-The electric field at g is zero.

E-Charge Q3 is the largest positive charge.                            

F-Q1 is a negative charge.

Explanation / Answer
