In hydrogen atom, if $\mathrm{V}_{\mathrm{n}}$ and $\mathrm{V}_{\mathrm{p}}$ are orbital velocities in $\mathrm{n}^{\text {th }}$ and $\mathrm{p}^{\text {th }}$ orbit respectively, then the ratio $\mathrm{V}_{\mathrm{p}}: \mathrm{V}_{\mathrm{n}}$ is
- A$\mathrm{p}: \mathrm{n}$
- B$\mathrm{n}: \mathrm{p}$
- C$\mathrm{p}^2: \mathrm{n}^2$
- D$\mathrm{n}^2: \mathrm{p}^2$
✓ Correct answer: B
