Question

Select the correct curve(s).
If v = velocity of electron in Bohr's orbit
r = Radius of electron n Bohr's orbit
P.E = Potential energy of electron in Bohr's orbit
K.E = Kinetic energy of electron in Bohr's orbit

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A
B
C
D

We know,
velocity of an electron in Bohr's orbit v $\propto$ $\frac{Z}{n}$
radius of electron in Bohr's orbit r $\propto$ $\frac{n^2}{Z}$

Potential energy P.E $\propto$ $-\frac{Z^2}{n^2}$

Kinetic energy K.E $\propto$ $\frac{Z^2}{n^2}$
