Question

The figure shows the equipotential contours in the plane of two point charges. The labels on the contours are in V. Determine for each of the following statement whether it is true or false. There is a point along the line y = 0 and between x = -10 and +10 where the potential is zero. There is no point along the line y=0 and between x=-10 and +10 where the field is zero. The two charges are in the ratio 2:3 The above charge configuration can be described as an electric dipole. The electrostatic potential energy of a negative charge increases as it is brought from a to b. No work is done in moving a charge from c to d.

Explanation / Answer

Here two charges are positive in nature and charge at x=-10 is less in magnitude than the charge at x=+10

1) False.

2) True.

3) Here kq1/42 = kq2/82 => q2=4q1

So answer is False

4) False

5) change in potential energy = -1.6*10-19*(1.8-1.4) = -ve

So answer is False

6) True
