Consider an electron $\mathrm{m}_{\mathrm{e}}=9.1 \times 10^{-31} \mathrm{kg}$ having energy 13.6 eV , confined in an infinite potential well. If the potential energy inside the well is zero, the expectation value for the square of the electron speed, $\left\langle\mathrm{v}^{2}\right\rangle$ , is
(a)$3 \times 10^{12} \mathrm{m}^{2} \mathrm{s}^{-2}$
(b)$4.3 \times 10^{18} \mathrm{m}^{2} \mathrm{s}^{-2}$
(c)$4.7 \times 10^{12} \mathrm{m}^{2} \mathrm{s}^{-2}$
(d)$4.7 \times 10^{31} \mathrm{m}^{2} \mathrm{s}^{-2}$
