Question:medium
Velocity of \( \text{I}^{\text{st}} \) orbit of hydrogen according to Bohr theory is \( v \), then what is the velocity of \( 3^{\text{rd}} \) orbit of hydrogen?
Velocity of \( \text{I}^{\text{st}} \) orbit of hydrogen according to Bohr theory is \( v \), then what is the velocity of \( 3^{\text{rd}} \) orbit of hydrogen?
Show Hint
Remember the key proportionalities for Bohr orbits:
Radius $r \propto \frac{n^2}{Z}$
Velocity $v \propto \frac{Z}{n}$
Energy $E \propto -\frac{Z^2}{n^2}$
Radius $r \propto \frac{n^2}{Z}$
Velocity $v \propto \frac{Z}{n}$
Energy $E \propto -\frac{Z^2}{n^2}$
