Physics

The physical quantity that has no dimensions is:


ANSWER

strain


SOLUTION

Angular velocity $$=M^{0}L^{0}T^{-1}$$
Linear momentum $$= mv$$ $$=M^{1}L^{1}T^{-1}$$
Angular momentum $$= mvr =$$ $$M^{1}L^{2}T^{-1}$$
Strain $$=\dfrac{\Delta L}{L}=\dfrac{M^{0}L^{1}T^{0}}{M^{0}L^{1}T^{0}}=M^{0}L^{0}T^{0}$$
