Question

s.i unit for young modulus

Answer 1

Answer: N/m^2 or Pa

Explanation:

s.i unit for Young’s modulus is N/m^2 since,

Y(i.e. Young’s modulus)= FL/AΔL

Dimensions of FL/AΔL are

[MLT^-2][L]/[[L^2][L]

= [ML^2T^-2]/[L^3]

= [ML^-1T^-2]

= kg/ms^2

= Pa

Now, Pa = Pressure which is equal to Force/ Area which is equal to N/m^2

Thus the s.i unit is N/m^2 or Pa
