To find the expression for the radius of the orbit, we can rearrange the equation mvr = nh/2π to solve for r:
r = nh/2πmv
Since the mass of the electron (m) and Planck's constant (h) are constants, we can simplify the expression further:
r = n(h/2πm)v
We know that the velocity of the electron in a circular orbit is related to the radius of the orbit by the equation v = ωr, where ω is the angular velocity of the electron. The angular velocity can be expressed as ω = v/r.
Substitute v = ωr into the expression for r:
r = n(h/2πm)(ωr)
r = n(h/2πm)ωr
Now, we can solve for the radius of the orbit:
r = n(h/2πm)ωr
r = n(h/2πm)ωr
1 = n(h/2πm)ω
r = h/2πmω
Therefore, the expression for the radius of the orbit is r = h/2πmω.

The angular momentum of an electron in a circular path is given by:
$$mvr=nh/2π$$
where:
- m is the mass of the electron - v is the speed of the electron - r is the radius of the orbit - n is an integer (0, 1, 2, 3, ...)
Solving for the radius of the orbit, we get:
$$r=\frac{nh}{2πmv}$$
This expression gives the radius of the orbit for a given value of n. The radius of the orbit increases as n increases.
