A) \[\frac{1}{r}\]and \[\frac{1}{{{r}^{2}}}\]
B) \[\frac{1}{{{r}^{2}}}\] and \[\frac{1}{r}\]
C) \[\frac{1}{{{r}^{2}}}\] and \[\frac{1}{{{r}^{3}}}\]
D) \[\frac{1}{{{r}^{3}}}\] and \[\frac{1}{{{r}^{2}}}\]
Correct Answer: D
Solution :
Electric field and electric potential at a general point at a distance r from the centre of the dipole is \[{{E}_{g}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{p}{{{r}^{3}}}\sqrt{(3\,{{\cos }^{2}}\theta +1)}\] and \[{{V}_{g}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\,\,\frac{p\,\cos \theta }{{{r}^{2}}}\]
