Two charges 𝑞1=4𝜇𝐶 and 𝑞2=−7𝜇𝐶 are separated by a distance of 5.0𝑚. Please do calculate the electric potential at the midway of the two charges.

Answer 1

Hey Adrian,

You likely have the formula V = kq/r. So, what you can do is solve this equation twice (once for each charge) and just add the numbers together. Keep in mind that your r will be 2.5m for each, so this reduces algebraically to V = k (q₁ +q₂)/ r

^^That equation only works because r is the same for each charge.
