A) \[{{E}_{1}}={{E}_{2}}\]
B) \[{{E}_{1}}=2{{E}_{2}}\]
C) \[{{E}_{2}}=2{{E}_{1}}\]
D) None of the above
Correct Answer: B
Solution :
The electric field strength in end on position, is given by \[{{E}_{2}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{2p}{{{d}^{3}}}\] ... (i) Electric field strength on broad side on position or on equatorial position is \[{{E}_{2}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{2p}{{{d}^{3}}}\] ... (ii) From Eqs. (i) and (ii), we get \[\frac{{{E}_{1}}}{{{E}_{2}}}=\frac{2}{1}\Rightarrow \,{{E}_{1}}=2{{E}_{2}}\]
