Measurement of length, Mass and Time

The percentage error in measurements of length and time period is 2% and 1% respectively . The percentage error in measurements of 'g' is

The percentage errors in the measurement of length and time period of a simple pendulum are 1% and 2% respectively. Then, the maximum error in the measurement of acceleration due to gravity is

Express the following derived units in terms of the fundamental units of length, mass and time.

If the fundamental units of length, mass and time are doubled, the unit of force will

Acceleration due to gravity is to be measured using simple pendulum. If a and b are percentage errors in the measurement of length and time period respectively, then percentage error in the measurement of acceleration due to gravity is

The acceleration due to gravity is measured on the surface of earth by using a simple pendulum. If alphaandbeta are relative errors in the measurement of length and time period respectively, then percentage error in the measurement of acceleration due to gravity is

In a particular measurement system, the units of length, mass and time are chosen as 10 cm, 10 g and 0.1 s respectively. What is the unit of force in this system in terms of the units in SI system?

In a given system of unit standard measurement of mass is 100 gm standard measurement of length is 200 cm and standard measurement of time is 5 sec 10 J energy in the given system of unit has value N, then value of N is

In measures of lengths

Assertion (A): Temperature is a fundamental quantity in SI system. Reason (R ): In other systems of measurement only mass, length and time are fundamental quantities.
