Question

In which of the following balances, standard weights are not required? (1) Beam balance (2) Physical balance (3) Grocer's balance (4) Digital balance​

Answer 1

Digital Balance does not require standard weights to measure weights.

Explanation:

• Weighing of an object was done earlier by comparing the object with an object of same weight.

• So, objects of specific weights are kept as standards and they were termed as standard weights.

• There are different mechanism to measure the weights of an object.

• They are by Beam balance, physical balance, grocer's balance and digital balance.

• In beam balance, two pans are kept above beam and the pans will move up and down when the weight of the object is not equal with the standard weights.

• In physical balance, the pointer will be attached to a rod whose two ends are connected with pans.

• The pointer will move towards the direction of the pan with higher weights.

• In Grocer's balance also, we need standard weights to compare the object with the standard object.

• But in digital balance, only the object is putted on the balance and the weight of it will be shown.

• So, digital balance is the one which does not require standard weights.
