Work done by the Sun on the Earth

Classical Mechanics

The Earth takes 1 year to complete its orbit around the Sun. Treating the orbit as perfectly circular, find the net work done on the Earth by the Sun in $\frac14$ of a year. Give your answer to three significant figures.

Assumptions:

Mass of the Earth = $5.97\times 10^{24} \text{kg}$

Distance from Sun to Earth = $1.50\times 10^{11} \text{m}$

1 Earth year = 365 Earth days

1 Earth day = 24 hours
