Question

Electric field at a distance r from an electric dipole on its axis is ${\vec{E}}_{1}$ and at distance 2r on its perpendicular bisector is ${\vec{E}}_{2}$ then:

$| {\vec{E}}_{2} | = | {\vec{E}}_{1} | / 4$

$| {\vec{E}}_{2} | = | {\vec{E}}_{1} | / 2$

$| {\vec{E}}_{2} | = | {\vec{E}}_{1} | / 8$

$| {\vec{E}}_{2} | = | {\vec{E}}_{1} | / 16$
