In the relation , is the pressure, z the distance, k is Boltzmann constant and is the temperature, the dimensional formula of will be
View answer and explanation
Correct option: A
Option A ([M⁰L²T⁰]) is correct because the exponent in the exponential term must be dimensionless, allowing us to determine the dimensions of β.

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
