Question

Two point charges $+1\mu C\text{and}-1\mu C$ are placed at points $(0,-0.1m)\text{and}(0,+0.1m)$ respectively in }$XY$ plane. Then, choose the correct statement's from the following.

• A. The electric field at all points on the Y axis has the same direction.
• B. The dipole moment is $0.2\mu C-m\text{along}+X$ direction
• C. No work has to be done in bringing a test charge from infinity to the origin.
• D. Electric field at all points on the X axis is along + Y axis.

Answer 1

Answer: (C), (D)

The correct options are
