Physics
Three point charges lie in a straight line along the y-axis. A charge of q1 = − 9.0 μC is at y = 6.0 m, and a charge of q2 = −8.0 μC is at y = − 4.0m. The net electric force on the third point charge is zero. Where is this charge located?
Which of the following is an example of a reversible process? A hand pump is rapidly compressed and the pressure and temperature in the pump rise. The pump is held in position as the temperature drops to the ambient temperature. A car engine burns fuel to produce motion of the car and exhausts the 140°C waste products of the combustion into the 20°C atmosphere. An ice cube at 0°C melts while in a water bath at 0°C. A stick of dynamite explodes. A high pressure air tank at room temperature has its valve opened and the gas in the tank rushes out until the pressure in the tank is equal to atmospheric pressure.

Two small, conducting spheres, initially uncharged, are brought into contact and given a total charge of 5.00x10^4 electrons. The spheres are then separated until their centers are 12.0 cm apart. Assuming the total number of electrons on the spheres remains the same as they are separated: a) What is the magnitude of the force that each sphere exerts on the other? b) Is the force attractive or repulsive?
