Answer:
118.06 days
Explanation:
d = distance of the center of moon from surface of planet = 2.315 x 10⁵ km = 2.315 x 10⁸ m
R = radius of the planet = 4.15 x 10³ km = 4.15 x 10⁵ m
r = center to center distance between the planet and moon = R + d
M = mass of the planet = 7.15 x 10²² kg
T = Time period of revolution around the planet
Using Kepler's third law
![T^{2}=\frac{4\pi ^{2}r^{3}}{GM}](https://tex.z-dn.net/?f=T%5E%7B2%7D%3D%5Cfrac%7B4%5Cpi%20%5E%7B2%7Dr%5E%7B3%7D%7D%7BGM%7D)
![T^{2}=\frac{4\pi ^{2}(R + d)^{3}}{GM}](https://tex.z-dn.net/?f=T%5E%7B2%7D%3D%5Cfrac%7B4%5Cpi%20%5E%7B2%7D%28R%20%2B%20d%29%5E%7B3%7D%7D%7BGM%7D)
![T^{2}=\frac{4(3.14)^{2}((4.15\times 10^{5}) + (2.315\times 10^{8}))^{3}}{(6.67\times 10^{-11})(7.15\times 10^{22})}](https://tex.z-dn.net/?f=T%5E%7B2%7D%3D%5Cfrac%7B4%283.14%29%5E%7B2%7D%28%284.15%5Ctimes%2010%5E%7B5%7D%29%20%2B%20%282.315%5Ctimes%2010%5E%7B8%7D%29%29%5E%7B3%7D%7D%7B%286.67%5Ctimes%2010%5E%7B-11%7D%29%287.15%5Ctimes%2010%5E%7B22%7D%29%7D)
T = 1.02 x 10⁷ sec
we know that , 1 day = 24 h = 24 x 3600 sec = 86400 sec
T = ![(1.02 \times 10^{7} sec)\frac{1 day}{86400 sec}](https://tex.z-dn.net/?f=%281.02%20%5Ctimes%2010%5E%7B7%7D%20sec%29%5Cfrac%7B1%20day%7D%7B86400%20sec%7D)
T = 118.06 days
