PhysicsEasysingle choice

An electron rotates in a circle around a nucleus having positive charge Ze. Correct relation between total energy (E) of electron to its potential energy (U) is :

Options:

Answer:

Solution:

$F = \frac{k ( Ze ) ( e )}{r ^{2}} = \frac{mv ^{2}}{r} KE = \frac{1}{2} mv^{2} = \frac{1}{2} \frac{K ( Ze ) ( e )}{r} PE = - \frac{K ( Ze ) ( e )}{r} TE = \frac{K ( Ze ) ( e )}{2 r} - \frac{K ( Ze ) ( e )}{r} = \frac{- K ( Ze ) ( e )}{2 r} TE = \frac{PE}{2} 2 TE = PE$
