The dimensions of a rectangular block measured with calipers having least count of 0.01 cm are 5 mm 10 mm 5 mm. The maximum percentage error in the measurement of the volume of the block is
View answer and explanation
Correct option: A
0.05
Option D (0.05) is correct because the maximum percentage error is calculated by dividing the least count by the smallest measurement.

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
