Electric Potential And Potential Difference

The electric potential at a point due to a point charge is given by the formula: Where: - is the electric potential, - is Coulomb's constant ( ), - is the charge, - is the distance from the charge. At the point where the potential is zero, the potentials due to both charges must cancel each other out. Therefore, the total electric potential at that point is zero: For the two charges: - The charge is at a distance from the point where the potential is zero. - The charge is at a distance from the same point. The electric potentials at the point due to the charges are: Simplifying this equation: Cross-multiply to solve for : Thus, the electric potential is zero at a point 0.67 m from the charge.
