Question

Solid angle $d \Omega=\frac{d A}{r^2}$ has dimensions $\left[\mathrm{M}^0\left\llcorner^0 \mathrm{~T}^0\right]\right.$
Strain $=\frac{\Delta l}{l}$ h

Vedclass · Accepted Answer

strain and angle

Vedclass · Answer

Solid angle $d \Omega=\frac{d A}{r^2}$ has dimensions $\left[\mathrm{M}^0\left\llcorner^0 \mathrm{~T}^0ight]ight.$
Strain $=\frac{\Delta l}{l}$ has dimensions $\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^0ight]$
Angle measured in radians is also dimensionless $\left[\mathrm{M}^0 \mathrm{~L}^0 \mathrm{~T}^0ight]$
$	heta=\frac{l}{r}$

The quantities which have the same dimensions as those of solid angle are:
