Based on Heisenberg's uncertainty principle, the uncertainty in the velocity of the electron to be found within an atomic nucleus of diameter $\displaystyle 10^{-15} \mathrm{~m}$ is $\displaystyle \_\_\_\_$× $\displaystyle 10^9 \mathrm{~ms}^{-1}$ (nearest integer) [Given : mass of electron $\displaystyle =9.1 \times 10^{-31} \mathrm{~kg}$, Plank's constant $\displaystyle (h)=6.626 \times 10^{-34} \mathrm{Js}$ ] (Value of $\displaystyle \pi=3.14$ )
