A quantity x is given by ( 1 F v 2 / W L 4 ) in terms of moment of inertia I , force F , velocity v , work W and length L . The dimensional formula for x is same as that of :

Options

  1. Aplanck's constant
  2. Bforce constant
  3. Cenergy density
  4. Dcoefficient of viscosity

Correct answer

C. energy density

Step-by-step solution

IFv 2 WL 4 = M 1 L 2 M + L 1 T - 2 L 1 T - 2 2 M 1 L 2 T - 2 L 4 = M 1 L - 2 T - 2 L 3 = M 4 L - 1 T - 2 = Energy density
