Two point charges

+1 \mu \mathrm{C}

and

-1 \mu \mathrm{C}

are placed at points

(0,-0.1 \mathrm{~m})

and

(0,+0.1 \mathrm{~m})

respectively in XY plane. Then, choose the correct statement/s from the following.

Options

AThe electric field at all points on the Y axis has the same direction.
BThe dipole moment is $0.2 \mu \mathrm{C}-\mathrm{m}$ along +X axis direction.
CNo work has to be done in bringing a test charge from infinity to the origin.
DElectric field at all points on the X axis is along +Y axis.

Correct answer

D. Electric field at all points on the X axis is along +Y axis.
