NEET Physics Question - Gravitation - Acceleration Due to Gravity and its variation

Two types of balances, the beam balance and the spring balance are commonly used for measuring weight at shops. If we are at the moon, we can continue to use :

Only the beam type balance without any change

Only the spring balance without any change

both the balances without any change

Neither of the two balances without making any change

Solution:

On the Moon, the acceleration due to gravity is weaker (about \( \frac{1}{6} \) of that on Earth), affecting how a spring balance measures weight.

A spring balance relies on the gravitational force to measure weight based on the stretch of the spring, so it would give a lower reading on the Moon.

In contrast, a beam balance compares masses based on equilibrium, unaffected by gravity. Thus, it can be used without any change to measure weight accurately on the Moon.
