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