Question

How is a mass of an object determined using a beam balance?

Answer 1

1. Physical balance is an instrument that is used to measure the mass of an object.
2. By making use of the principle of moments, we can measure the gravitational mass of an object
3. An object of mass $m_1$ is placed on left pan of balance and standard weight of $m_2$ (which is called standard weight) is placed in the right pan to keep the beam horizontal for a beam balance,$a_1=a_2$, then $m_1=m_2$.
