Question

4. If the mass of Earth is 6 x 10 kg and its radius is
6400 km, calculate the gravitational force of the
Earth on a child of mass 10 kg sitting in a room.
Assume G = 6.7 x 10-N m’kg ? [Ans. 98.1 N]​

Answer 1

Answer:

Step-by-step explanation:

The mass of the earth is 6.0 xx 10^(24) kg and its radius is 6.4 xx 10^(6) m. How much work ... What will be the gravitational potential energy of the body on the Earth's surafce ? G = 6.67 xx 10^(-11) Nm^(2) kg^(-2). ... G=6.67×10-11Nm2kg-2. ... A geostationary satellite orbits the Earth at a height of nearly `36,000 km
