Question
Question: In the electric field of a charge Q, a charge q<sub>0</sub> is moved from A to B, and from A to C, (...
In the electric field of a charge Q, a charge q0 is moved from A to B, and from A to C, (distance AC = 2AB) then-
A
Work done is greater along the path AC than along AB
B
Work done is zero in both the cases
C
Work done is the same but non zero in both the cases
D
Work done is less along the path AC than along AB
Answer
Work done is the same but non zero in both the cases
Explanation
Solution
Q VB = VC ¹ VA & WA® B = q0 (VB –VA) ,
WA®C = q0(VC – VA) Ž WA®B = WA®C ¹ 0,
