( $\varepsilon_0$ is permittivity of free space, $R \gg$ dipole size)
$(1)$ $R =\left(\frac{ p _0}{4 \pi \varepsilon_0 E _0}\right)^{1 / 3}$
$(2)$ The magnitude of total electric field on any two points of the circle will be same
$(3)$ Total electric field at point $A$ is $\vec{E}_A=\sqrt{2} E_0(\hat{i}+\hat{j})$
$(4)$ Total electric field at point $B$ is $\vec{E}_B=0$
$(c=$ speed of electromagnetic waves)

($h = 6.62 \times {10^{ - 34}} J-sec; 1 eV = 1.6 \times {10^{ - 19}}J; c = 3 \times {10^8}\,m/s)$
