(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the potential difference between y_{i}= -5cm and y_{f}=5cm in the uniform electric field E = ( 20,000{ i } - 50,000 { j } )V/m?

2. Relevant equations

∆V = V(s_{f}) - V(s_{i}) = -∫ E_{s}ds

with the limits of the integral being s_{f}and s_{i}

3. The attempt at a solution

I tried doing the integral, resulting in (E^{2})/2, and then multiplying proceding as so:

E= √ (20000^{2}+ 50000^{2}) = 53851.64807

(E^{2})/2 = 14500000 = x

x |_{0.05,-0.05}= -{x(0.05) - x(-0.05)} = -{2[x(0.05)]} = -1450000 = incorrect

any help?

thanks!
