Question

Determine the gravitational potential of a body of mass 80 Kg whose
gravitational potential energy is 5 x 10°J on the surface of earth.​

Answer 1

Answer:

....

.................

Answer 2

The gravitational potential is $8.33\times10^{-16}\ J$

Explanation:

Given that,

Mass of body = 80 kg

Potential energy $P.E=5\times10^{10}\ J$

We need to calculate the gravitational potential

Using formula of gravitational potential

$U=\dfrac{GM}{r}$

Put the value into the formula

$U=\dfrac{6.67\times10^{-11}\times80}{6.4\times10^{6}}$

$U=8.33\times10^{-16}\ J$

Hence, The gravitational potential is $8.33\times10^{-16}\ J$
