For an electron in 2p-orbital, radial probability function 4πr²R² as a function of r is given by

C onsider the following figures A and B indicating distribution of charge density (electron probability ) with distance r

Select the correct statement(s).

Which orbital gives an electron, a greater probability being found close to the nucleus?

Hamiltonian operator is the sum of two energy operators. These are

Angular nodes in 4s- suborbit is equal to radial nodes in

at any point is proportional to

There is formation of in all five nodes (including terminal nodes) in a string of 12 cm. Thus, wavelength of the waves formed is 

For x -axis , wave function () can be written as

Thus, Schrodinger wave equation along x-axis can be written as : 

The Schrodinger wave equation for H-atom is 

where, a₀ is Bohr’s radius. If radial node in 2s is at distance r₀, then

The de Broglie wavelength associated with a ball of mass 200 g and moving at a speed of 5 metres/hour, is of the order of (h = 6.625 x 10^-34 J s) is

What will be the wavelength of an electron moving with 1/10th of velocity of light?

Match the column I with column II and mark the appropriate choice.
