Question

23. Lunar Gravity Compare the force holding a

Answer 1

Explanation:

Given

mass of the rock is 10 kg

Force requires to hold the rock is equal to its weight

Weight is given by the product of mass and acceleration due to gravity

Weight on the earth surface

$\Rightarrow W_e=10\times 9.8\\\Rightarrow W_e=98\ N$

Weight on the moon surface

$\Rightarrow W_m=1.6\times 10\\\Rightarrow W_m=16\ N$

So, the force holding the rock on earth is approximately 6 times the force on the moon.
