Two statements, one Assertion (A) and the other Reason (R) are given. Choose the correct option.
Assertion: 2-aminoethanoic acid and p-aminobenzene sulphonic acid can exist as Zwitter ions while p-aminobenzoic acid cannot.
Reason: When the acid group is a relatively strong proton donor and the \(-\mathrm{NH}_2\) group is sufficiently basic it can accept a \(\mathrm{H}^{+}\)ion from the acid group to form the dipolar ion.

A vertical circular coil of radius \(0.1 \mathrm{~m}\) and having \(10\) turns carries a steady current. When the plane of the coil is normal to the magnetic meridian, a neutral point is observed at the centre of the coil. If \(B_{H}=0.314 \times 10^{-4} \mathrm{~T}\), the current in the coil is

Two statements, one Assertion and the other Reason, are given. Choose the right option.
Assertion: The Standard Electrode potential, \(\mathrm{E}^0 \mathrm{Co}^{3+} / \mathrm{Co}^{2+}\) is greater than \(\mathrm{E}^0 \mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}\).
Reason: \(\mathrm{Co}^{3+}\) ions are less stable in aqueous medium than \(\mathrm{Fe}^{3+}\) ions which has stable \(\mathrm{d}^5\) configuration
