Solved Examples on Unit of Weight
Example 1: The weight of a body is 700 N in SI units. Find its weight in CGS units.
Solution:
We know that,
1 N = 105 dyne
700 N = 700 × 105 dyne
700 N = 7 × 107 dyne
Thus, we get weight in CGS units is found to be 7 x 107 dyne.
Example 2: The mass of a man is 40 kg. Find its weight on earth.
Solution:
Given, Mass (m) = 40 kg
We know that, Acceleration due to gravity on earth (g) = 9.8 ms-2
And, Weight (W) = mg = 40 × 9.8 = 392 N
Thus, weight of the man on earth is found to be 392 N.
Unit of Weight
Unit of Weight is Newton represented as N, which is also known as the force of gravity on a mass. Weight of the body is the gravitational force by which the earth or any other planet attracts the body. Other weight units are pound-force, metric ton, slug, quintal, kilogram-force (kgf) and dyne.
In this article, we will discuss the definition of weight, unit of weight, conversion between the unit of weight in various systems, and some sample problems related to the unit of weight.
