Just wondering how do you calculate the potential difference between Pt A and B in the picture.(adsbygoogle = window.adsbygoogle || []).push({});

Value of E: 95 N/C

AB=0.33 m

the angle is 42

I researched and found an equation V= Ercostheta

but I've never seen or used this equation before. Will I get the potential difference between A and B just by pluggin the values in?

V=(95)(0.33)cos(42)
