The dimensional formula for Young’s modulus is
Options
(a) [ML⁻¹T⁻²]
(b) [M⁰LT⁻²]
(c) [MLT⁻²]
(d) [ML²T⁻²]
Correct Answer:
[ML⁻¹T⁻²]
Explanation:
Young’s modulus Y=Stress/Strain=(Force/Area)/(elongation/Iength)
Y=[MLT⁻²][L]/[L²][L] = [ML⁻¹T⁻²]

(d) [ML²T⁻²]
[ML⁻¹T⁻²]
Young’s modulus Y=Stress/Strain=(Force/Area)/(elongation/Iength)
Y=[MLT⁻²][L]/[L²][L] = [ML⁻¹T⁻²]
