state the principle on which a beam balance works

Somnath physics · Accepted Answer

Dear Student,
The working principle of a beam balance is:
moment The beam will be balanced only when the
moments of force on both the sides of the balance are equal

That is, (m1g)r1 =
(m2g)r2
'g' is the acceleration due to gravity

state the principle on which a beam balance works.
