An object at the surface of earth (at a distance r from the center of earth) weighs 166 n. what is its weight (in n) at a distance 4r from the center of earth? round your answer to the nearest tenth.

The weight at a distance 4R from the center of earth is 10.37 N.

Explanation:

Given that,

Weight = 166 N

Distance = 4R

Let m be the mass of the object.

We know that,

Mass of earth

Gravitational constant

Radius of earth

We need to calculate the weight at a distance 4 R from the center of earth

Using formula of gravitational force

Put the value in to the formula

Now, Again using formula of gravitational

Hence, The weight at a distance 4R from the center of earth is 10.37 N.

the correct choice is a .
