Answer:
Velocity of electron will be equal to [tex]v=4.711\times 10^5m/sec[/tex]
Explanation:
We have given kinetic energy of electron [tex]KE=1.01\times 10^{-19}J[/tex]
Mass of electron [tex]m=9.1\times 10^{-31}kg[/tex]
We have to find velocity of electron
Kinetic energy of electron is equal to [tex]KE=\frac{1}{2}mv^2[/tex], here m is mass and v is velocity
So [tex]1.01\times 10^{-19}=\frac{1}{2}\times 9.1\times 10^{-31}\times v^2[/tex]
[tex]v=4.711\times 10^5m/sec[/tex]
So velocity of electron will be equal to [tex]v=4.711\times 10^5m/sec[/tex]
