When an electron with charge .e. and mass .m. moves with velocity .v.

1.	When an electron with charge .e. and mass .m. moves with velocity .v. around the nucleus having nuclear charge .Z. in a circular orbit of radius .r., the potential energy of electron is
Answer» `(ZE^(2))/(R)` `(Ze^(2))/(r^2)` `(-Ze^2)/(r)` `(mv^2)/(r)` SOLUTION :PE = `-(Ze^2)/(r)`
