Electric Potential at a Point in Space Due to a Point Charge Q

two electrons...

Question

two electrons held at distance r are released from rest . maximum kinetic energy obtained by electron is _.

Options are

A. Zero

B.ke^2/r

C.ke^2/2r

D.ke^2/r^2

Open in App

Solution

Dear student Option c is the answer
e^2/2r
Solution
Potential energy of electron in nth orbit of radius r in H - atom U=−e^2/r (in CGS)
∵K.E=1/2|P.E|⇒K=e^2/2r
