the earth revolves around the sun with an angular velocity of 2*10-7 rad/s in a circular orbit of radius 1.5*108 km. the force exerted by sun on earth is

F = mv2rhere, angular velocity ,ω=vr .So ,v=rωF= mrω2r=mrω2Given ;m , mass of the earth = 6×1024 kgr= 1.5×108 km=1.5×1011mω=2×10-7 rad/sSo ,F=mrω2=6×1024×1.5×1011×2×10-7 2  =36×1021 N
