An 8.50 kg point mass and a 13.0 kg point mass are held in place 50.0 cm apart. A particle of mass mm is released from a point between the two masses 18.0 cmcm from the 8.50 kg mass along the line connecting the two fixed masses. Required:
Find the magnitude of the acceleration of the particle.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
