Question

The range of masses we study in Physics is

A. ${{10}^{-27}}$kg to ${{10}^{60}}$kg
B. ${{10}^{-27}}$kg to ${{10}^{55}}$ kg
C. ${{10}^{-30}}$ kg to ${{10}^{55}}$ kg
D. ${{10}^{-30}}$ kg to ${{10}^{60}}$kg

Answer 1

The mass of the electron is considered to be the least mass of the range of the masses we study in Physics, whereas, the mass of the known observable universe (universal component) is to be the greatest mass of the range of the masses we study in Physics.

Complete step by step answer:
The terms mass and weight are different, but many times are considered to be the same. The mass is a fixed/constant quality and the mass of particular remains the same throughout the universe. Whereas, the weight is a variable quantity and the weight of the particular changes with respect to the gravitational attraction between the bodies/objects.

The weighing machines are used to measure the mass of bodies having the mass range nearer to humans.
The mass of the celestial bodies is measured using the gravitational formula.
The spectrograph is used to measure the mass of atomic and subatomic particles.
The electron is considered to be the particle with least mass of ${{10}^{-30}}$ kg. The mass of the known universe (observable universe) is considered to have the highest mass of ${{10}^{55}}$ kg.
