For a uniform electric field vecE = E_(0)(hati), if the electric potential at x = 0 is zero, then the vaJut of electric potential at x = +x will be ..... .

Answer»

`xE_(0)`
`-xE_(0)`
`x^(2)E_(0)`
`-x^(2)E_(0)`

Solution :The POTENTIAL DIFFERENCE at x =0 and x =+x
`V_((x))-V_((0))=-int_(0)^(x)E_(0)dx=-E_(0)[int_(0)^(x)dx]`
`=-E_(0)[x]_(0)^(x)=-E_(0)x`
but `V_((0))=0`
`:. V_((x))= -E_(0)x`
