a.The schrodinger wave equation for hydrogen atom is `psi_(2s) = (1)/(4sqrt(2pi)) ((1)/(a_(0)))^((3)/(2)) (2 - (r_(0))/(a_(0)))e^((-(r )/(a))`
When `a_(0)` is Bohr's radius Let the radial node in `2s` be n at Then find `r_(0)` in terms of `a_(0)`
b. A base ball having mass `100 g` moves with velocity `100 m s^(-1) `.Find the value of teh wavelength of teh base ball

Answer

A, B, C

Explanation

b. `lambda = (h)/(mv)`("de Broglie's equation")`
`= (6.626 xx 10^(-34))/(100 xx 10^(-3) xx 100) = 6.626 xx 10^(-35) m `
