​

Answer 1

Answer:

in the presence of a glass strip a magnet remains unaffected.

Answer 2

Answer:

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

In absence of magnetic field, the degeneracy of p− orbitals is 3. In presence of magnetic field, the degeneracy of orbitals remains the same if the orbitals can be inter converted by symmentric operation like rotation, reflection etc. Since p-orbitals are similar to each other, they can be inter converted by symmetric rotation. Due to this, in presence of magnetic field also, the p-orbitals are three-fold degenerate....
