Homework Statement
An electric field is given by E_x = (5 kN/C) x^3. Find the potential difference between the points on the x-axis at x= 1 m and x = 5 m. Answer in units of kV.
Homework Equations
V = -Ed
The Attempt at a Solution
V1 = -5*10^6 N/C * 1 = -5*10^6 volts
V2 = -5*10^6 * 5 = -25*10^6 volts = -2.5*10^7 volts
V2 - V1 = -25*10^6 -(-5*10^6) = -20*10^6 = -2.0*10^4 kV
I also tried cubing x and got -6.2e+5 but that is also wrong.
