An ideal parallel-plate capacitor consists of a set of two parallel plates of area a separated by a very small distance d. when this capacitor is connected to a battery that maintains a constant potential difference between the plates, the energy stored in the capacitor is u0. if the separation between the plates is doubled, how much energy is stored in the capacitor? an ideal parallel-plate capacitor consists of a set of two parallel plates of area a separated by a very small distance d. when this capacitor is connected to a battery that maintains a constant potential difference between the plates, the energy stored in the capacitor is u0. if the separation between the plates is doubled, how much energy is stored in the capacitor? u0/2 u0 u0/4 4u0 2u0

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
