7PRACTICE PROBLEM
During an experiment, a parallel plate capacitor is used to launch a 4.5 g ball vertically upwards by converting the electrical energy to mechanical energy. The capacitor, initially charged to a voltage of 145 V, undergoes an ultrafast discharge, propelling the ball to a height of 2.8 m. Determine the capacitance of the capacitor, neglecting any dissipation effect.
