Question

the escape speed from a planet x is 165 m/s. calculate the density of the planet in kg/m3 if the diameter of the planet is 225 km

Answer 1

$\huge\boxed{Hey\:Mate!!}$

formula to be applied is

Vs = Rp√{8/3π (rho)G}

here,

vs = scape velocity of that planet

vs = 165m/s given

Rp= radius of planet

Rp = 112.5Km (given)

rho= density of planet

G= Universal Gravitational constant

G= 6.67×10^-11 N-m^2/Kg^2

Now, put the values and get your answer

165 = 112.5 √ 8/3 × 3.14 (rho) × 6.67×10^-11

rho= approx 3.86 ×10^9 Kg/m^3

hope it helps!!☺️
