Q. The difference between a spring balance and in ordinary balance in which there are two parts are:

A
Spring balance measures Mass of the body and ordinary balance measures weight of the bodY
B
Spring balance measures weight of the body and ordinary balance measures mass of the bodY
C
Both the balances measures mass of the body
D
Both the balances measure Weight of the body
Solution:

Spring balances or spring scales calculate mass by first measuring weight by balancing the force due to gravity against the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of one or more known masses.
