Question

. A positive and negative charge of the same magnitude lie on a long straight line.

What is the direction of ⃗ for points on this line that lie between the charges?
​

Answer 1

Explanation:

The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. ... As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.
