$ML{T^{ - 2}}$
$M{L^2}{T^{ - 2}}$
$M{L^2}{T^{ - 1}}$
If $G$ is universal gravitation constant and $g$ is acceleration due to gravity, then dimensions of $\frac{G}{g}$ will be ...................
A small steel ball of radius $r$ is allowed to fall under gravity through a column of a viscous liquid of coefficient of viscosity $\eta $. After some time the velocity of the ball attains a constant value known as terminal velocity ${v_T}$. The terminal velocity depends on $(i)$ the mass of the ball $m$, $(ii)$ $\eta $, $(iii)$ $r$ and $(iv)$ acceleration due to gravity $g$. Which of the following relations is dimensionally correct
The dimensions of shear modulus are
Dimensions of kinetic energy are
Dimension of $R$ (Resistance) is
