Question

Hello, I am so frustrated with this problem, is it possible to receive a little help on how to answer it?

Answer 1

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 .

Step-by-step explanation:

Now the accelaration towards the ground of moon B is equivalent to the acceleration due to gravity of Moon B.

Thus,

`\begin{gathered} g_B=(GM)/(R^2) \\ \Rightarrow g_B=(6.67*10^(-11)*1.5*10^(20))/((2*10^5)^2) \\ \Rightarrow g_B=0.250m/s^2 \end{gathered}`

Conclusion:

Thus the rate at which the laser would accelerate towards the ground is

`0.25m/s^2`
