here mass of sun, mass of earth's and the distance is given
so using formula
F= GMm/d^2
F=6.7×10^-11 Nm/kg^2×2×10^30kg×6×10^24kg/(1.2×10^-11m)^2
F=6.7×2×6×10^-11+30+24/1.44×10^-22
F= 80.4×10^43-(-22)/1.44
F= 3.6× 10^22N
and according to third law of motion to every action there is equal and opposite reaction

Force of gravity between two objects is given by:
F=GMm/r2
where G=6.674*10−11Nm2/kg2 G=6.674*10−11Nm2/kg2 is the gravitational constant.
Mass of the Sun, M=2*1030kg M+2*1030kg
Mass of the Earth, m=6*1024kgm=6*1024kg
Separation, r=1.2*1011m
F= 5.583e +66
