Physics point charges electric potential?
A point charge of +2.4 µC is located at (2.5 m, 3.2 m). A second point charge of -3.0 µC is located at (−2.1 m, 1.0 m).
Figured out the first question, which was the electric potential at the origin = -6289 V.
Need help with second question...
At what coordinate (x0,y0) between the two charges is the electric potential equal to zero?
x0 = ?
y0 = ?

Hello McLaude, just use this formula to get the potential at the origin due to Q at a point whose co-ordinate is (x,y)
V = 9*10^9 * Q / (x^2 +y^2)^1/2
As potential is scalar, we have to simply add them algebraically. Potential due to positive is +ve and due to negative is -ve. Micro means 10^-6
Second part could be solved by equating the potential due to both to be equal. Hope you would do on your own
