${\mathrm{E}}_{\mathrm{n}}\text{ and }{\mathrm{J}}_{\mathrm{n}}$ denote the total energy magnitude and the angular momentum of an electron in the n^th allowed orbit of a Bohr atom, Then

• A

  ${\mathrm{E}}_{\mathrm{n}}\propto {\mathrm{J}}_{\mathrm{n}}$

• B

  ${\mathrm{E}}_{\mathrm{n}}\propto 1/{\mathrm{J}}_{\mathrm{n}}$

• C

  ${\mathrm{E}}_{\mathrm{n}}\propto {\mathrm{J}}_{\mathrm{n}}^2$

• D

  ${\mathrm{E}}_{\mathrm{n}}\propto 1/{{\mathrm{J}}_{\mathrm{n}}}^2$
