Gas in a cylinder similar to the one shown in the figure moves a piston with area 0.223 m2 as energy is slowly added to the system. If 2.80 103 J of work is done on the environment and the pressure of the gas in the cylinder remains constant at 1.01 105 Pa, find the displacement of the piston.
A positive charge Q1 = 3.00 µC is in the origin and a negative charge Q2 = -5.00 µC is at point x = 11m. Find the position of point P between the charges, where the electric potential equals zero.
