Solution


Q.

In a measurement, it is asked to find modulus of elasticity per unit torque applied on the system. The measured quantity has dimension of [MaLbTc]. If b = –3, the value of c is __________.          [2025]

Ans.

(0)

[Modulus of elasticity] =ML–1T–2

[Torque] =ML2T–2

[Modulus of elasticity per unit torque] =ML–1T–2ML2T–2=L–3.
