Question
As the orbit number increases, the K.E. and P.E. for an electron
Options
A.both increases.
B.both decreases.
C.K.E. increases but P.E. decreases.
D.P.E. increases but K.E. decreases.
Solution
$K.E. = \frac{1}{2}mv^{2},P.E. = - mv^{2}\text{ and }V \propto \frac{1}{n}$
Therefore, with increase in orbit number, K.E. decreased but P.E. increases.
