Question

4. Mass of the Earth is (5.97 x 1024) kg and mass of Jupiter is (1.90 x 1027) kg. What is the
total mass of the two?
[Hint: Total
mass =
[5.97 x 1024 + 1.90 x 1027] kg
= (5.97 x 1024 + 1.9 x 1024 x 103) kg
= (5.97 + 1.9 ~ 103) 1024
(5.97 + 1900) 1024 kg]
kg​

Answer 1

Answer:

Mass of Jupiter=1.9×1027㎏=M1

Mass of Sun=1.99×1030㎏=M2

Mean distance of Jupiter from Sun=7.8×1011m=r

G=6.67×10−11N㎡㎏−2

Gravitational Force, F=r2GM1M2

F=(7.8×1011)26.67×10−11×1.9×1027×1.99×1030

F=4.16×1023N
