Two large metal plates of area 1.4 m2 face each other. they are 4.8 cm apart and have equal but opposite charges on their inner surfaces. if the magnitude e of the electric field between the plates is 52 n/c, what is the magnitude of the charge on each plate? neglect edge effects.

Calculate the work done by an external agent during an isothermal compression of 1.00 mol of oxygen from a volume of 22.4 l at 10∘c and 1.0 atm pressure to 16.8l

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
