A) \[2q\cdot E\] and minimum
B) \[q\cdot E\] and \[p\cdot E\]
C) Zero and minimum
D) \[q\cdot E\] and maximum
Correct Answer: C
Solution :
In the given condition angle between \[\vec{p}\] and \[\vec{E}\] is zero. Hence potential energy \[U=-\,pE\cos 0=-\,pE\,=\min .\] Also in uniform electric field \[{{F}_{net}}=\text{ }0\].You need to login to perform this action.
