266445 For atomic model of hydrogen atom given by Niels Bohr, match the following proportionalities: | Column-I | Column-II | | :--- | :--- | | a. Angular momentum | i. $1 / n$ | | b. Velocity of electron | ii. $n^2$ | | c. Radius of orbit | iii. $1 / n^2$ | | d. Energy of electron | iv. n. |

266446 Given below are two statements: Statement I: \(\vec{A} \times \vec{B}\) is perpendicular to both \(\vec{B} \times \vec{A}\) as well as A- Statement II : \(\vec{A}+\vec{B}\) as well as \(\vec{A}-\vec{B}\) lie in the plane containing \(\vec{A}\) and \(\vec{B}\), but \(\vec{A} \times \vec{B}\) lies perpendicular to the plane containing \(\vec{A}\) and \(\vec{B}\). In the light of the above statements, choose the most appropriate answer from the options given below :
