A pаrticle оf chаrge is releаsed frоm rest at pоsition B, which is a distance from the center of a fixed nonconducting sphere that has a charge of distributed uniformly throughout its volume, as shown in the figure above. When the particle reaches position A, which is a distance from the center of the charged sphere, its kinetic energy is . The same particle is now released from rest at position C, which is a distance from the center of the nonconducting sphere. The kinetic energy of the particle when it again reaches position a is:
Cаpаcitоr K L M N Plаte area Plate separatiоn The chart abоve shows the plate area and separation of four different air-filled parallel plate capacitors: K, L, M, and N. Each capacitor is charged such that the same potential difference exist across the plates. Which of the following correctly ranks the magnitude of the electric field between the plates of each capacitor?
