Question

The acceleration of electron in the first orbit of hydrogen atom is ______.

विकल्प

• `(4pi^2"m")/"h"^2`

• `"h"^2/(4pi^2"mr")`

• `"h"^2/(4pi^2"m"^2"r"^2)`

• `("m"^2"h"^2)/(4pi^2"r"^3)`

Answer 1

The acceleration of electron in the first orbit of hydrogen atom is `"h"^2/(4pi^2"m"^2"r"^2)`.

Explanation:

From mvr = `"nh"/(2pi) , "v" = "nh"/(2pi"mr")`

Acceleration, a = ` "v"^2/"r" = ("n"^2"h"^2)/(4pi^2 "m"^2 "r"^2(r))`
