Question

h=fv2÷l find the dimensions of h. F is force v is velocity L is angular momentum

Answer 1

Explanation:

Given H = Fv2÷l

Units of

F = N = kgm/s^2

V = m/s

l = kgm^2/s

Therefore

H= (kgm/s^2 × m/s ×2)÷ kgm^2/s

H= (kgm^2/s^3) × s/kgm^2

Therefore

Unit of H = s^2

So dimensional formula =

[M^0 L^0 T^2]
