Answer & Solution

Correct Answer

(A) \(5.76 \times 10^7 \mathrm{NC}^{-1}\)

Step-by-step Solution

Detailed explanation

Given, charge of dipole, \(q=500 \times 10^{-6} \mathrm{C}\) Separation between charges, \(2 a=10 \mathrm{~cm}\) \[ =10 \times 10^{-2} \mathrm{~m} \] Distance of location from mid point of axis, \[ r=25 \mathrm{~cm}=25 \times 10^{-2} \mathrm{~m} \] \(\because\) Electric field on…
