Speed of an electron in Bohr's 7^th orbit for Hydrogen atom is 3.6 × 10^6 m / s. The corresponding speed of the electron in 3^rd orbit, in m / s is:
Speed of an electron in Bohr's $\displaystyle 7^{\text {th }}$ orbit for Hydrogen atom is $\displaystyle 3.6 \times 10^6 \mathrm{~m} / \mathrm{s}$. The corresponding speed of the electron in $\displaystyle 3^{\mathrm{rd}}$ orbit, in $\displaystyle \mathrm{m} / \mathrm{s}$ is :
