Question

If V_n and Vp are orbital velocities in n^th and p^th orbit respectively, then the ratio V_p: V_n is ______.

Options

• `"n"^2/"p"^2`

• `"p"/"n"`

• `"p"^2/"n"^2`

• `"n"/"p"`

Answer 1

If V_n and Vp are orbital velocities in n^th and p^th orbit respectively, then the ratio V_p: V_n is `underline("n"/"p"`.

Explanation:

Velocity V = `"e"^2/ (2in_0 "hn")`

`therefore "V"  alpha  1/"n"`

`therefore "V"_"p"/"V"_"n" = "n"/"p"`
