Question

Example 1. Find the gravitational force between
earth and an object of 2 kg mass placed on its
surface. (Given, mass of the earth = 6 x 1024 kg and
radius of the earth = 6.4 x 106 m)​

Answer 1

Explanation:

g=m1*m2/r^2

g= 2*6*10^24/6.4*10^6

g= 12*10^24-6/6.4

g= 12*10^18/6.4

g=1.875*10^18

g= 1875 *10^15

plz mark me as brainlest

Answer 2

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
