Question

The lines show the equipotential contours in the plane of three point charges, Q1, Q2, and Q3. The values of the potentials are in kV as indicated for the +5, 0, and -5 kV contours. The positions of the charges are indicated by the dots.

The letters are on the equipotential contours. Answer either true or false

Charge Q2 is the negative charge with largest magnitude.
Q1 is a negative charge.
The force on a proton at g points to the bottom of the page.
The electric field at k is zero.
Charge Q3 has the largest magnitude of all.
The electric field at i is stronger than at j.

Calculate the magnitude of the work required to move a charge of -0.39
