A) -4V
B) 4V
C) zero
D) 6.4V
Correct Answer: B
Solution :
[b] \[{{W}_{el.}}=q({{V}_{i}}-{{V}_{f}})\] or \[6.4\times {{10}^{-19}}=-1.6\times {{10}^{-19}}\left( {{V}_{A}}-{{V}_{B}} \right)\] or \[{{V}_{A}}-{{V}_{B}}=-4V\] or \[{{V}_{A}}-{{V}_{C}}=-4V\text{ }\left( \because {{V}_{B}}={{V}_{C}} \right)\] or \[{{V}_{C}}-{{V}_{A}}=4V\]You need to login to perform this action.
