Chapter 8: Q.14 (page 199)

A satellite orbiting the moon very near the surface has a period of $110$ min. What is free-fall acceleration on the surface of the moon?

Short Answer

Expert verified

$g_{m o o n} = 1.58 m / s^{2}$

Step by step solution

Given information

Given in the question that, A satellite orbiting the moon very near the surface has a period of $110$ min.

Period of

Given:

$T_{sat} = 110 \min$

$T_{sat} = 110 \min \times \frac{60 s}{1 \min}$

$T_{sat} = 6600 s$

Step 3:A satellite is orbiting the moon

When a satellite is orbiting the moon at a constant speed, the only force that is acting on it is the gravitational force from the moon.

$\sum F = m g_{m o o n} = m a_{r}$

$m ̸ g_{moon} = m ̸ a_{r}$

$g_{moon} = \frac{v_{s a t}^{2}}{r}$

$g_{moon} = \frac{v_{sat}^{2}}{1.74 \times 10^{6}}$ (2)

$v_{sat} = \frac{2 π r}{T}$

$v_{sat} = \frac{2 π \times 1.74 \times 10^{6}}{6600}$
$v_{s a t} = 1.66 \times 10^{3} m / s (2)$

From (1) and(2)

$g_{moon} = \frac{{[1.66 \times 10^{3}]}^{2}}{1.74 \times 10^{6}}$

$g_{m o o n} = 1.58 m / s^{2}$

Final answer

The free-fall acceleration on the surface of the moon is

$g_{m o o n} = 1.58 m / s^{2}$
