Two charged particles are moving with equal velocities of 4.70 m/s in the +x-direction. At one instant of time the first particle with a charge of 2.70 μC is located at x = 0 and y = +3.10 cm, and the second particle with a charge of 7.80 μC is located at x = 0 and y = -3.10 cm. 1. What is the y-component of the magnetic force on the first particle due to the second?2. How fast would the charges have to be moving for the magentic force to be equal in magnitude to the electric force?

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
