Homework Statement
Two small metal spheres, A and B, of mass mA = 6.5 g and mB = 12.7 g have equal positive charges of 8 μC. The spheres are connected by a non-conducting string of negligible mass and with length d = 1.4 m, which is much greater than the radii of the spheres.
a) What is...

Two positive charges, each with Q = +10 µC, are fixed to the x-axis at x = +a and x = -a, where a = 4 m.
(a) Find the electric potential at point A on the y-axis where (xA, yA) = (0, b) and b = 5 m. Take the zero of potential to be at infinity.
(b) A...
