1.	How many times does light travel faster in vacuum than an electron in bohr first orbit of hydrogen atom?
Answer» 13.7 times 67 times 137 times 97 times Solution :`v=(Z)/(n)xx2.188xx10^(8)cm//sec` `v_(1)=(1)/(1)xx2.188xx10^(8)cm//sec` `("VELOCITY of light")/("Velocity of electron")=(3XX10^(10))/(2.188xx10^(8))=137` times.
