The dimensional formula for young's modulus is
A$M{L^{ - 1}}{T^{ - 2}}$
B${M^0}L{T^{ - 2}}$
C$ML{T^{ - 2}}$
D$M{L^2}{T^{ - 2}}$
Solution
Young's modulus $Y =\frac{\text { stress }}{\text { strain }}$
Dimension of $Y =\frac{ M L ^{-1} T ^{-2}}{ M ^{0} L ^{0} T ^{0}}$$=\left[ M L ^{-1} T ^{-2}\right]$
Dimension of $Y =\frac{ M L ^{-1} T ^{-2}}{ M ^{0} L ^{0} T ^{0}}$$=\left[ M L ^{-1} T ^{-2}\right]$
