Practice Problems 1. A metal sphere with a charge of -2.50 X 10-9 C is 1.50 cm to the left of a second metal sphere with a charge of +1.50 × 10-9 C. A third metal sphere of -1.00 × 10-9 C is situated 2.00 cm to the right of the second charged sphere. If all three charges form a line, determine the net electrostatic force on the second sphere. 2. In the situation described above, if the first and third spheres remain at their original positions, where should the second sphere be situated so that the net electrostatic force on it would be zero?
