Question

i)
[L'M'T?] is the dimensional formula for


​

Answer 1

Answer:

Modulus of elasticity is given by     Y=AF.ΔLL

Dimension of force  F=[MLT−2]

Dimension of Area  A=[L2]

Dimension of length  L=[L]

Thus dimension of modulus of elasticity   Y=[L2][L][MLT−2][L]=[ML−1T−2]

Answer 2

Answer:

[L1M1T-2] is the dimensional formula for force
