A torque meter is calibrated to reference standards of mass, length and time each with accuracy. After calibration, the measured torque with this torque meter will have net accuracy of
View answer and explanation
Correct option: B
Option B () is correct because the accuracy of torque is related to the product of mass, length, and time, and their errors add up.

Statement-I: Random errors can be positive or negative.
Statement-II: Cause of random errors are uncertain. An object is moving through the liquid. The viscous damping force acting on it is proportional to the velocity. Then dimension of constant of proportionality is The error due to parallax is a: 2.34 is obtained by rounding of the number The dimensional formula of self-inductance is The dimension of is that of
