A quantity x is given by (1Fv2/WL4 ) 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 :
  1. planck's constant
  2. force constant
  3. energy density
  4. coefficient of viscosity

Solution

IFv2WL4=M1L2M+L1T-2L1T-22M1L2T-2L4=M1L-2T-2L3=M4L-1T-2= Energy density
