Question

what is the force of gravity on a body of mass 150 kg lying on the surface of the earth mass of the earth is equal to 6 into 10 power 24 kg radius is equal to 6.4 into 10 power 6 metre



give the answer in fast plz​

Answer 1

1465.57 N

Explanation:

As we know,

$\sf \: f \: = \dfrac{GMm}{r {}^{2} }$

here, F = Force of gravity

G = Universal Gravitation Constant

M = Mass of One obeject

m = Mass of Another object

R = Distance between them

Units :

All are in S.I

Solution :

Mass of Earth$\sf (M)= 6 \times {10}^{24} \: kg$

Mass of Body$\sf (m) = 150 \: kg$

Distance between them

i. e Radius of earth$\sf (R)=6.4\times 10{}^{6} \:m$

$\sf G = 6.67 \times 10 {}^{ - 11} N \: m {}^{2} /kg {}^{2}$

Calculation :
