A) 5 V
B) 2.5 V
C) 1 V
D) 0 V
Correct Answer: B
Solution :
Suppose potential at point A is -10 V and potential at point B is V volt. Now, given \[{{W}_{AB}}\,\,=\,\,100\,J\] As, \[{{\operatorname{W}}_{AB}}\,\,=\,\,q({{V}_{B}}-{{V}_{A}})\] \[50 =\,\,4 \left[ V-\left( -10 \right) \right]\] \[50 =4(V+10)\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\operatorname{V}=12.5 -10\] \[\operatorname{V} =\,\,2.5 V\]You need to login to perform this action.
