Question

Calculate the force of gravity (g) acting on your friend of mass 60 kg. given mass of earth is 6 x 10 24 kg and radius of the earth is 6.4 x 10 6 m.

Answer 1

Answer:

First the force of gravity is equal to GMm/Distance^2

from question m = 60kg

M=6×10^24kg

suppose the man is on the surface of earth and the distance from centre of earth is equal to the radius of earth so Distance ' d '= 6.4×10^6 m

now putting values in formula

G =6.67 ×10^-11Nm^2kg^-2

now

F=6.67×10^-11×60×6×10^24/6.4×10^6×6.4×10^6

.F=5.86×10=58.6N
