A) only on q
B) only on x
C) on qx
D) on \[\frac{q}{x}\]
Correct Answer: C
Solution :
Electric potential due to electric dipole at axial line \[{{E}_{axial}}=\frac{k(2qx)}{({{r}^{2}}-{{x}^{2}})}\]where r is the distance of observation point from centre of dipole. For general point \[{{E}_{q}}=\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{2qx\cos \theta }{{{r}^{2}}}\] So, the value of potential depends on \[qx.\]
