Question

The lines show the equipotential contours in the plane of three point charges, Qi, 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 Q1 9 olts Qa em 1 The letters are on the equipotential contours. The force on a proton at g points to the bottom of the page D Qi is a negative charge. Charge Q3 has the largest magnitude of all The electric field at k is zero. Charge Q2 is the negative charge with largest magnitude The electric field at i is stronger than at j

Explanation / Answer

The elecctric field at i is stronger than at j becuse i is closer to equipotential contour +5 .
