Question

When mass of the body balances the mass of a standard weight

a) The beam becomes vertical and pointer horizontal,

b) The beam becomes oblique and the pointer vertical

c) The beam turns right and pointer left, d) The beam becomes horizontal and the pointer vertical​

Answer 1

Answer:

A beam balance is the simplest instrument to measure mass (weight). In a beam balance, the mass of an object is measured by comparing it with standard masses called standard weights. A simple beam balance consists of a straight beam of metal (generally iron), supported at its centre with the help of an iron loop. A pointer is fixed at the centre of the iron loop. Two identical pans are are suspended at equal distances from the centre, at the two ends of the beam.
