**drwls**, Monday, February 11, 2008 at 2:11amTo get the potential energy at any point P, add up the k*Qi/ri terms, where Qi is the charge of the ith particle and ri is it's distance away from point P. The sign of Q is important.

At the center, ri = sqrt2 meters for each corner particle

Do both problems the same way, but changing the value of one of the charges, qi. The other three charges stay the same.

**Anonymous**, Monday, February 11, 2008 at 1:37pmthere is a typo. the last charge is suppose to be -5c10^-6C

Can you check my work and see what I did wrong? Thank you!

Work:

K(5x10^-6C)/1 + K(3x10^-6)/1 + K(3x10^-6)/1+ K(-5x10^-6C)/1+K(5x10^-6C)/sqrt(2) + K(3x10^-6)/sqrt(2) + K(3x10^-6)/sqrt(2)+ K(-5x10^-6C)/sqrt(2)
