Given,
Mithra is a unknown planet which has two moons A and B in circular orbits around it.
The datas of the two moons are given as:
To find:
Rate of acceleration of the laser towards the ground when it is thrown from the surface of Moon B .
Explanation:
Now the accelaration towards the ground of moon B is equivalent to the acceleration due to gravity of Moon B.
Thus,
[tex]\begin{gathered} g_B=\frac{GM}{R^2} \\ \Rightarrow g_B=\frac{6.67\times10^{-11}\times1.5\times10^{20}}{(2\times10^5)^2} \\ \Rightarrow g_B=0.250m/s^2 \end{gathered}[/tex]
Conclusion:
Thus the rate at which the laser would accelerate towards the ground is
[tex]0.25m/s^2[/tex]
