For any H like system, the ratio of velocities of electron in I, II & III orbit e.e.,`V_(1):V_(2):V_(3)` will be:

For any H like system, the ratio of velocities of electron in I, II & III orbit i.e., V_(1):V_(2):V_(3) will be:

For the given conductor the drift speed of electrons at cross section I, II and III are v_(d_1) , v_(d_2) , " and v_(d_3) , then

The velocity of an electron in the first orbit of H atom is v. The velocity of an electron in the 2nd orbit of He^+ atom.

The velocity of an electron in the first orbit of H-atom is v. The velocity of an electron in the 2nd orbit

Show that the ratio of velocities of equal masses in an inelastic collision when one of masses is stationary is v_(1)/v_(2)=(1-e)/(1+e)

Considering the wavelengths of electron and proton to be equal,the ratio of their velocities (v_(e)/(v_(p) would be: (mass of electron =9.1times10^(-31)kg, mass of proton =1.67 times10^(-27)kg

If velocity of an electron in I orbit of H atom is V , what will be the velocity of electron in 3^(rd) orbit of Li^(2+)
