1.	The electric field in a region is given by \(\vec E = \left( {Ax + B} \right)\hat i\), where E is in NC-1 and x is in meters. The values of constants are A = 20 SI unit and B = 10 SI unit. If the potential at x = 1 is V1 and that at x = -5 is V2, then V1 – V2 is:
A.	320 V
B.	-48 V
C.	180 V
D.	-520 V
Answer» D. -520 V
