Two capacitors have equal capacitance. The first capacitor is holding twice as much charge as the second capacitor. How much energy does the first capacitor hold relative to the second?.

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

What is friction? how does it affect the motion of an object?
