    Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : If oxygen ion (O−2)\left( O^{- 2} \right) and Hydrogen ion (H+)\left( H^{+} \right)enter normal to the magnetic field with equal momentum, then the path of O−2O^{- 2} ion has a smaller curvature than that of H+H^{+}. Reason R : A proton with same linear momentum as an electron will form a path of smaller radius of curvature on entering a uniform magnetic field perpendicularly. In the light of the above statement, choose the correct answer from the options given below
