In Region of Electric field Given by `vec(E)=(Ax-B)hat(I)`. Where `A=20` unit and `B=10` unit. If Electric potential at `x=1m` is `v_(1)` and at `x=-5m` is `v_(2)`. Then `v_(1)-v_(2)` is equal to

A

`-520V`

B

`320V`

C

`-48V`

D

`180V`

Text Solution

Verified by Experts

The correct Answer is:
D
`vdv" "," "dV=-Edx," "underset(V_1)overset(V_2)(int)dV=-overset(-5)underset(1)(int)(20x+10)dx`
`V_(2)-V_(1)=-180," "V_(1)-V_(2)=180V `
