Question
The acceleration of electron in the first orbit of hydrogen atom is ______.
Options
`(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)`
MCQ
Fill in the Blanks
Solution
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))`
