Given `r_(n+1)-r_(n-1)=2r_(n),`where `r_(n)-r_(n-1)=r_(n+1),` are Bohr radius for hydrogen atom in `n^(th),(n-1)^(th)` shell respectively. Calculate the value of n.

different between nth and (n + 1) th Bohr's radius of hydrogen atom is equal to (n = 1) th Bohr's radius. The value of n is

Given that r_(n-1)+r_(n)=r_(n+1) where r represents Bohr's orbit for (n-1)^("th"),n^("th") and (n+1)^("th") orbit, then n is

Difference between n^(th) and (n+1)^(th) Bohr's radius of H atom is equal to it's (n-1)^(th) Bohr's radius. The value of n is

Difference between n^(th) and (n+1)^(th) Bohr's radius of H atom is equal to it's (n-1)^(th) Bohr's radius. The value of n is

If .^(n+1)C_(r+1):^(n)C_(r):^(n-1)C_(r-1)=11:6:3 , find the values of n and r.

If .^(n)C_(r-1): .^(n)C_(r): .^(n)C_(r+1)=3:4:5 , find the values of n and r.

There are two long co-axial solenoids of same length l. The inner and other coils have redii r_(1) and r_(2) and number of turns per unti length n_(1) and n_(2) respectively .The reatio of mutual inductance to the self - inductance of the inner- coil is : (A) n_(1)/n_(2) (B) n_(2)/n_(1).r_(1)/r_(2) (C) n_(2)/n_1.r_2^2/r_1^2 (D) n_(2)/n_(1)

If ^n P_r=^n P_(r+1)a n d^n C_r=^n C_(r-1,) then the value of n+r is.

If n P_r=^n P_(r+1) and n C_r=^n C_(r-1,) then the value of (n+r) is.
