Question

I'm trying to find the potential energy of a planet using formula G M(sun) x m(planet) / r. I have given G - newton's graviational constant at 6.67 × 10−11 m3 kg−1 s−2 , MSun is the mass of the Sun: 1.99 × 1030 kg, m planet is the mass of the planet at 5.97 x 10^24 and r is the distance from the Sun at 147.1 x 10^6 km

Answer 1

Answer:

$-5.39\times10^{33} J$

Explanation:

Potential energy =

$-\frac{GMm}{r}\\=-\frac{6.67\times10^{-11}\times1.99\times10^{30}\times5.97\times10^{24}}{147/1\times10^{9}}\\=-5.39\times10^{33} J$
