An electric field is expressed as\[E=2\widehat{i}+3\widehat{j}\]. Find the potential difference\[({{V}_{A}}-{{V}_{B}})\] between two points A and B whose position vectors are given by \[{{r}_{A}}=\widehat{i}+2\widehat{j}\text{ }and\text{ }{{r}_{B}}=2\widehat{i}+\widehat{j}+3\widehat{k}.\]

A) -1 V                             

B) 1 V

C) 2 V                              

D) 3 V
