A small metal sphere has a mass of m = 0.15g and a charge of q = -23.0nC. It is 10.0cm directly above an identical sphere that has the same charge. This lower sphere is fixed and cannot move. If the upper sphere is released, it will begin to fall. a) What is the electric force on the upper sphere due to Coulomb's Law? b) What is the magnitude of its initial acceleration? c) Why is this only the initial acceleration? Draw a sketch. find an expression for net force, then use F = ma. PROBLEM 1. A small metal sphere has a mass of m = 0.15 g and a charge of q = -23.0 nC. It is10.0 cm directly above an identical sphere that has the same charge. This lower sphere is fixedand cannot move. If the upper sphere is released, it will begin to fall. What is the electric forceon the upper sphere due to Coulomb's Law? What is the magnitude of its initial acceleration?Why is this only the initial acceleration? [Draw a sketch. Find an expression for the net force,then use F = ma.]
