A body weighs 63N on the surface of the earth. What is the gravitational force on it due to the earth at the height of 3200km from the earth's surface? (Radius of the earth is 6400 km) (take g=10m/s^2 & G=6.67×10^-11)

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
