Two point charge `+-q` are placed on the axis at `x= -a` and `x= +-a`, as shown in fig.
(i) Plot the variation of E along the x-axis.
(ii) Plot the variation of E along the y-axis.

Text Solution

Verified by Experts

(i) Variation of E along the x-axis is shown in fig.
(ii) Variation of E along the y-axsi is shown in fig.
This case field will be maximum at origin beacause at origein filed due to both charge is directly added.
