Question

The physical quantity that does not have the dimensional formula [ML-1T-2] is (A) force (B) pressure (C) stress (D) modulus of elasticity

Tardigrade Admin · Accepted Answer

As, force = mass × acceleration ⇒ Force =[ M ] ×[ M 0 L 1 T -2] ⇒ Force =[ M 1 T .1 T -2] So, the force does not have the dimensional formula [ M L -1 T -2]

Q. The physical quantity that does not have the dimensional formula $[M L^{- 1} T^{- 2}]$ is

force

pressure

stress

modulus of elasticity

energy density

As, force $=$ mass $\times$ acceleration
$\Rightarrow$ Force $= [M] \times [M^{0} L^{1} T^{- 2}]$
$\Rightarrow$ Force $= [M^{1} T_{.}^{1} T^{- 2}]$
So, the force does not have the dimensional formula $[M L^{- 1} T^{- 2}]$
