Statement-I: The number of significant figures in is 1 while in it is 3.
Statement-II: Zeros before a non-zero significant digit are not counted while zeros after a non-zero significant digit are counted.
Statement-II: Zeros before a non-zero significant digit are not counted while zeros after a non-zero significant digit are counted.
View answer and explanation
Correct option: A
Statement-I is true and statement-II is true
Option A (Statement-I is true and statement-II is true) is correct because the number of significant figures in 0.001 is 1, and in 0.100 it is 3, and the rule about zeros is correctly stated.

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
