An electron of mass 'm' is rotating in first Bohr orbit of radius 'r' in hydrogen atom. The orbital acceleration of the electron in first orbit (h = Planck's constant).
पर्याय
h/4 π2mr2
h/2 π2
h2/2π2 m2r2
h2/4π2 m2r2
MCQ
उत्तर
h2/4π2 m2r2
Explanation:
L = mvr = `"nh"/(2pi)`
`therefore "v" = "nh"/(2pi"mr")`
`=> "v"^2 = ("n"^2"h"^2)/(4pi^2"m"^2"r"^2)`
`=> "v"^2/"r" = ("n"^2"h"^2)/(4pi^2"m"^2"r"^3)`
