Discuss the symmetry between the laws of charles coulomb and sir isaac newton regarding forces

matt forgot to put the fabric softener in the wash. as his socks tumbled in the dryer, they became charged. if a small piece of lint with a charge of +1.25 e -19 c is attracted to the socks by a force of 3.0 e -9 n, what is the magnitude of the electric field at this location?

suppose an electric field with a magnitude of 2.8 e 4 n/c at a certain location, points due south. if a charge of -4.0 e -6 c is brought to the location, what is the electrostatic force that acts on this c

In a steady-flow steam power plant system, two adiabatic high-pressure and low-pressure turbines ane used to generate power. superheated steam enters the high-pressure turbine at 8 mpa and 550°c. the steam expands in the high-pressure turbine to a saturated vapor at 3 mpa. in order to increase the powe generation of the power plant, another steam turbine working in a lower pressure ranges is deployed. the outlet vapor from the first turbine is heated up at a boiler to the temperature of 500 c at the constant pressure of first turbine's outlet (3 mpa). then, the vapor enters the second turbine and produces extra work. the exit conditions of the second turbine are 5o kpa and 90 percent quality. if the total power output of the power plant is 25 mw, determine a) the mass flow rate of the water (kg/s). b) heat transfer rate in the boiler (mw).
