Question

calculate the gravitational force on a body of mass 1 kg lying on the surface of earth given mass of Earth is 6*10"24"kg and radius of earth is 6400km

Answer 1

_/\_ Hello mate__ here is your answer -

Mass of Earth, M = 6 × 10^24 kg

Mass of object, m = 1 kg

Universal gravitational constant,

G = 6.7 × 10^−11 Nm^2 kg^−2

r = radius of the Earth (R) ( ob. is on the surface of earth)

r = R = 6.4 × 10^6 m

Therefore, the gravitational force

F = GMm / r^2

$=(6.7×10^-7×6×10^24 ×1)/(6.4×10^4)^2$

= 9.8 N

I hope, this will help you.☺

Thank you______❤

Answer 2

Answer:62.53*10⁹

Explanation: by putting value in this formula F=Gm¹m²/d² ,where G-6.67*10¹¹ , mass ¹ -1and mass ²6*10²⁴, distance 6400
