A) \[{{E}_{1}}={{E}_{2}}\]
B) \[{{E}_{1}}=2{{E}_{2}}\]
C) \[{{E}_{1}}=2{{E}_{2}}\]
D) none of these
Correct Answer: B
Solution :
In end on position, the electric field strength is given by \[{{E}_{1}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\times \frac{2p}{{{d}^{3}}}\] ?.(i) Electric field strength on broad side on position or on equatorial position is \[{{E}_{2}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\times \frac{p}{{{d}^{3}}}\] ??(ii) Now from equations (i) and (ii) \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{2}{1}\] or \[{{E}_{1}}=2{{E}_{2}}\]
