Question

[L² M¹ r^-2] are the dimensions of ______.

विकल्प

• torque

• force

• angular acceleration

• angular momentum

Answer 1

[L² M¹ r^-2] are the dimensions of torque.

Explanation:

Dimension of torque is [L² M¹ r^-2]

Torque = Force × Perpendicular distance

i.e., τ = F × r

∴ Dimensional formula of τ = [M L T^-2][L]

= [ML² T^-2]
