A) \[qaE\]
B) \[-qaE\]
C) \[q\sqrt{({{a}^{2}}+{{b}^{2}})}E\]
D) \[3qE\sqrt{{{a}^{2}}+{{b}^{2}}}\]
Correct Answer: B
Solution :
The work done is independent of the path followed and is equal to \[(qE)\,r,\] Where, r = displacement vector, \[PS=-ai-aj,\] while \[E=Ei\] Work \[=qE.\,\,r=-qaE\]You need to login to perform this action.
