ANSWER
Given conditions
Mass of earth (m
1
)=6×10
24
kg
Mass of moon (m
2
)=7.4×10
22
kg
Distance between earth and the moon (d)=3.84×10

km
Gravitational constant (G)=6.7×10

F is the force of gravitational between earth and moon
Substituting values in formula F=
(3.84×10

×6×10
24
×7.4×10

N
⇒F=20.2×10

N
Thus the gravitational force of attraction between earth and sun is 2.02×10
19
N.
