E, m, L and G denote energy, mass, angular momentum and gravitational constant respectively, has the dimensions of
View answer and explanation
Correct option: D
angle
Option D (angle) is correct because it involves finding the dimensions of , where E is energy, L is angular momentum, m is mass, and G is the gravitational constant. After substituting the dimensions of each quantity and simplifying, the result is dimensionless, which corresponds to an angle.

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
