Question

The acceleration due to gravity on the surfcae of a planet is one-fourth of the value on Earth. When a brass ball is brought to this planet, its:

• A. mass is halved
• B. weight is halved
• C. mass becomes one-fourth
• D. weight becomes one-fourth
• E. mass and weight remain the same

Answer 1

Answer: (D)

weight becomes one-fourth

We know that,
Weight $W=$ $mg$
So, $W\propto$ $g$
According to question,
$\frac{W_2}{W_1}=\frac{g/4}{g}$
$\frac{W_2}{W_1}=\frac{1}{4}$.
