Acceleration Due to Gravity and its variation: Practice Problem & Solution
An object is weighed at the equator using a physical balance and a spring balance. When the same object is taken to the pole, then corresponding readings on the physical balance and spring balance (also taken there) will respectively:
Solution Explained:
To solve this problem, we apply the core principles of Acceleration Due to Gravity and its variation. Understanding the underlying formula is key to arriving at the correct answer below:
A physical balance measures mass, which is constant everywhere. A spring balance measures weight, \(W = mg\). Since gravity \(g\) is greater at the poles, the spring balance reading increases.
