1. The problem statement, all variables and given/known data
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} ? 2. Relevant equations e=kq1q1/r^2 v= integral of E dot ds v=ed 3. 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

BTW, in that formula, d is the separation between the two points over which the potential change is measured, not a position. So you have two values of the electric potential at two values of x. What is the slope of this (linear) function? What is the direction of the electric field?
