A) The work done in figure (i) is the greatest
B) The work done in figure (ii) is the least
C) The work done is the same in figure (i), (ii) and (iii)
D) The work done in figure (iii) is greater than figure (ii) but equal to that in figure (i)
Correct Answer: C
Solution :
(c) The work done is the same in figure (i), (ii) and (iii) In all the three figures, \[{{V}_{A}}=20V\]and \[{{V}_{B}}=40\,V\] Work done in carrying a charge q from A to B is \[W=q\left( {{V}_{B}}-{{V}_{A}} \right)\] Hence, work done is same in all figures.You need to login to perform this action.
