Uncertainity in position of a particles of 15 gram in space is `10^(-5)`m. Hence uncertainity in velocity (m//sec) is` (h = 6.6 xx 10^(-34)Jsec)`

Explanation

(I ) `n=0 ,i=0 , m_(1) =+ 1//2 `
these set of quatum numbers are not possible as .n. cannot have value .0.
(ii ) n=2 , `I=1, m_1 =0, m_s = - 1//2`
` n=2 `
` I =0 to (n-1)`
`I =0=1`
For ` i=1 , m_1 =-1 , 0 ,+1`
so these quantum numbers are possible
(iii ) `n=0 , m_(1) =3 , m_(3) = +1//2 `
Not possible as ` m_1 =3` value here is not permissible
` m_(1)` has values `=- l ,0,..., +l`
Possible values of ` m _1 = -2 , -1,0,+1,+2`
(iv ) `n=3 , l=1 , m_1 =0 , m_s =-1//2`
Possible
