The point charges `Q` and `-2Q` are placed at some distance apart. If the electirc field at the location of `Q` is `E`, the electric field at the location of `-2Q` will be

Options

A. `-E/2`
B. `-(3E)/2`
C. `-E`
D. `-2E`

Answer

A

Explanation

In this question both the charges must be applying equal and opposite force on each other. Hence, the electric field intensity at the site of-2Q should be half of the value of field intensity at the site of charge Q.
