## Homework Statement

The electric potential in a region of uniform electric field is -1000 V at x = -0.900 m and + 1400 V at x = + 2.00 m. What is E_{x} ?

## Homework Equations

e=kq1q1/r^2

v= integral of E dot ds

v=ed

## The Attempt at a Solution

i am thinking i will use the equation V=Ed, so I would use V=-1000 and d equal to -.9m

then i have no idea what to do from there, any help is appreciated. thank you
