Problem 24P

CE The charge q1 in Figure 20-22 has the value +Q. (a) What value must q2 have if the electric potential at point B is to be zero? (b) With the value for q2 found in part (a), is the electric potential at point A positive, negative, or zero? Explain.

Step-by-Step Solution:

Solution 24 P:

Step 1 of 3:-

a)

Here we have to find the value of fro which the electric potential at point B will be zero.

Let’s take the configuration as a square of length “r”.

So, the distance between and point B can be found by pythagoras theorem.

.

The charge .

The electric potential at point B, due to charge is,

The electric potential at point B, due to charge is,
