Question

The earth has radius of 6,357,000 meters, and a mass of 5.972*1024 kilograms. An elephant has a mass of 6,000 kilograms. What would the force of gravity on the elephant, from the earth, be?

Answer 1

`F=5.91* 10^4\ N`

Step-by-step explanation:

Given that,

The radius o Earth, R = 6,357,000 m

Mass of the Earth, M = 5.972 × 10²⁴ kg

The mass of an elephant, m = 6000 kg

We need to find the force of gravity on the elephant. The force acting between two objects is given by :

`F=(GMm)/(R^2)\\\\F=(6.67* 10^(-11)* 5.972* 10^(24)* 6000)/((6,357,000 )^2)\\\\F=59141.51\ N\\\\F=5.91* 10^4\ N`

So, the required force of gravity on the elephant is
`5.91* 10^4\ N`.
