Question

The point charge Q and -2Qare placed at some distance apart. If the electric field at the location of Q is of Q is E. The electric field at the location of -2Q will be

Options

A.
B.- E
C.
D.- 2E

Solution

Field at Q is E. So. Force on Q = QE
This force will be applied on -2Q. Also according to Coulomb′s So, field at
- 2Q is
