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
