The Problem
A mass of 5 kg is first weighed on a balance at the top of a tower 20 m high. Then the mass is suspended from a 20 m high wire and reweighed. We need to find the difference between their weight.
Understanding the Problem
To solve this problem, we need to understand the concept of weight and how it is affected by the height or distance from the center of the Earth.
Weight is the force exerted on an object due to gravity. It is a vector quantity and is dependent on the mass of the object and the gravitational acceleration. The formula to calculate weight is given by:
Weight = mass × gravitational acceleration
The gravitational acceleration on Earth is approximately 9.8 m/s².
Solution
1. Calculate the weight of the mass at the top of the tower:
- Weight = mass × gravitational acceleration
- Weight = 5 kg × 9.8 m/s²
- Weight = 49 N
2. Calculate the weight of the mass when suspended from the wire:
- The height of the wire is 20 m.
- The weight at this height can be calculated using the same formula.
- Weight = mass × gravitational acceleration
- Weight = 5 kg × 9.8 m/s²
- Weight = 49 N
Answer
The weight of the mass is the same both at the top of the tower and when suspended from the wire. Therefore, the difference between their weights is zero.
A mass of 5 kg is first weighed on a balance at the top of a tower 20 m high. Then the mass is suspended from a 20 m high wire and reweighed. We need to find the difference between their weight.
