A) \[\frac{Kq}{r}\left( 1-\frac{2a\cos \theta }{r} \right)\]
B) \[\frac{2kq\cos \theta }{{{r}^{2}}}\]
C) \[\frac{Kq}{r}\]
D) \[\frac{Kq}{r}\left( 1+\frac{2a\cos \theta }{r} \right)\]
Correct Answer: D
Solution :
[d] \[V=\frac{Kq.2a\cos \theta }{{{r}^{2}}}+\frac{Kq}{r}=\frac{Kq}{r}\left[ \frac{2a\cos \theta }{r}+1 \right]\]You need to login to perform this action.
