A capacitor consists of a set of two parallel plates of area A separated by a distance d . This capacitor is connected to a batt
ery that maintains a constant potential difference V across the plates. If the separation between the plates is doubled, the electrical energy stored in the capacitor will be
On an incline, the force causing the ball to move downwards would be gravity. Additionally, the component of gravity causing this ball to move downwards would be mgsintheta. Hope this helps!
