Question

A container of rocks is brought back from the Moon's surface where the acceleration due to gravity is 1.62 meters per second^2. If the total mass of the container of rocks is 65.0 kilograms, what is its weight on Earth's surface?
A) 65.0 N

B) 105 N

C) 394 N

D) 638 N

Answer 1

Force at moon:-

Use Newtons second law

$\\ \rm\Rrightarrow F=ma=65(1.62)=105.3N$

Force at moon is one sixth of force at earth

Weight on earth;-

• 105.3(6)=631.8N
