A short electric dipole is placed along ...

A short electric dipole is placed along y-axis at the origin. The electric field vector at a point P on x-axis is `vec(E ) _(1)`. The dipole is rotated by `( pi)/(2)` at its position . Now, the electric field vector at point P is `vec(E )_(2)`. Select the correct alternative(s) `:`

A

`vec(E )_(2)= - vec(E )_(1)`

B

`vec(E )_(2)= - 2vec(E )_(1)`

C

`|vec(E )_(2)| = - 2|vec(E )_(1)|`

D

`vec(E )_(2) . vec( E )_(1)=0`
