Question

If an electron revolves around a proton, then its time period T is (R = radius of orbit) –

• A. µ R²
• B. µ R^3/2
• C. µ R³
• D. µ R

Answer 1

Answer: (B)

µ R^3/2

Answer 2

T =

$\left. \begin{array} { l } \mathrm { r } \propto \mathrm { n } ^ { 2 } \\ \mathrm { v } \propto 1 / \mathrm { n } \end{array} \right\rvert \, \mathrm { v } \propto \frac { 1 } { \sqrt { \mathrm { r } } }$ Ž T µ µ r^3/2
