Question

A physical balance measures small differences in mass up to _____ mg

Answer 1

A physical balance can weigh up to 0.001 mg of mass.

Thus, this type of balance can be used for analytical study of any solid or liquid matter, as it accurately measures all masses while taking the gravity of earth as a constant factor.

However, the balance measuring the smallest mass of 0.001 mg is termed as microbalance.

Answer 2

Least count is the minimum amount of mass or the quantity which is described in the body which can be measured by the body. The least amount of the quantity is known as least count. In a Physical beam balance the minimum amount of mass which is here the quantity which can be measured by the balance is 1mg.

Hence A physical balance measures small differences in mass up to 1 mg. It is the answer.
