Questions Related to measurement of mass

In a physical balance, when the beam is released with empty pans, the successive left and right turning points are obtained as 5; 6, 6 and 18, 18 respectively. After placing the substance whose mass is to be determined and when beam is released, the resting point obtained is 13. When 10 mg is added to the pan, the resting point is obtained as 11. If the mass at LRP is 60 g, the correct mass of the body corrected to a milligram is ______ g. 

  1. 59.996

  2. 56.5

  3. 59.99

  4. 56.599


Correct Option: A

State whether true or false.
The pointer of a spring balance will read zero when there is no load on the pan.

  1. True

  2. False


Correct Option: A
Explanation:

If no lead is applied to the spring balance, there will be no extension in the spring and hence the pointer will read zero in the spring balance. Thus the given statement is true.

The weight placed on the pan is a balance when HRP is obtained is 47.86 g. The difference between ZRP and HRP of the physical balance is 3. When 10 mg is added in its pan, the difference between HRP and LRP is obtained as 5. Determine the most accurate mass of the body.

  1. 478.672 g

  2. 34.73 g

  3. 47.866 g

  4. 47.532 g


Correct Option: C

A beam balance is used to measure the ________ of a body.

  1. weight

  2. mass

  3. force

  4. shape


Correct Option: B
Explanation:

A beam balance is used to measure the mass of the body precisely.

A knob at the baseboard can be used to raise or lower the _____of the physical balance

  1. beam

  2. weight 

  3. mass

  4. none


Correct Option: A

A spring balance gives the measure of the mass of a body. True or false.

  1. True

  2. False


Correct Option: B
Explanation:

Spring balance gives the measure of the weight of the body. Thus the given statement is false.

Point out the odd one out of the following
beam balance, spring balance,  physical balance 

  1. Spring balance

  2. Beam Balance

  3. Physical Balance

  4. None


Correct Option: A
Explanation:

Spring Balance is used to measure weight others used to measure mass

Name a common device, among the following, used to measure the weight of a body.

  1. Spring balance

  2. Beam balance

  3. Rheostat

  4. Potentiometer


Correct Option: A
Explanation:

Spring balance measures the weight of the body.

Name a common device, among the following, used to measure mass of a body.

  1. Physical balance

  2. Spring balance

  3. Barometer

  4. Speedometer


Correct Option: A
Explanation:

Physical balance is used to measure the mass of the body. Spring balance measures the weight of the body, barometer measures the pressure exerted by the gas and speedometer measures the speed of the vehicle.

Select the odd one out (mass, beam balance, kilogram, spring balance)

  1. beam balance

  2. mass

  3. spring balance

  4. kilogram


Correct Option: C
Explanation:

Beam balance is used to determine the mass of the body and kilogram is the SI unit of mass. Whereas spring balance is used to determine the weight of the body. Thus spring balance is the odd one out.
