A point dipole is located at the origin in some orientation. The electric field at the point (10 cm, 10 cm) on the\[x-y\]plane is measured to have a magnitude\[1.0\times {{10}^{-3}}V/m\]. What will be the magnitude of the electric field at the point (20 cm, 20 cm)?

A)  \[5.0\times {{10}^{-4}}V/m\]

B)  \[2.5\times {{10}^{-4}}V/m\]

C)  It will depend on the orientation of the dipole

D)  \[1.25\times {{10}^{-4}}V/m\]
