Question

Find the force of gravity on a mass of 60kg using Newton's law of gravitation. (Mass of Earth=6×10 to the power 24 kg, dist. =6.4×10 to the power 6 m)

Answer 1

Answer:586.230N

Explanation:

Here,

Mass of earth(M)=6×10^24 Kg

Mass of object(m)=60Kg

Distance between them(r)=6.4×10^6m

Now, force of gravity(F)=?

We know, F=GMm/(r^2)

={6.67×10^(-11)×6×10^24×60}/{6.4×6.4×10^12}

={6.67×36×10^14}/{40.96×10^12}

=240.12×10^14 / 40.96/10^12

=24012/40.96= 586.230 N
