A disc of mass M and radius R rolls without slipping on a horizontal surface (see figure). If the speed of its centre is v₀ , then the magnitude of the angular momentum of the disc about a fixed point P at a height 5 R / 2 above the horizontal surface

Options

1. Aincreases continuously as the disc moves away from P until it attains a constant value 5 2 M v₀ R .
2. Bdecreases continuously as the disc moves away from P until it attains a constant value 3 2 M v₀ R .
3. Cis constant and equal to M v₀ R .
4. Dis constant and equal to 2 M v₀ R .
