Question

Dimension of $\frac{h}{RC}$ is similar to ($h$ = plank's constant, $R$ = resistance, $C$ = capacitance)

• A. Linear momentum
• B. Force
• C. Angular momentum
• D. Torque

Answer 1

The correct option is D Torque

Bohr Model of Hydrogen $L=\frac{nh}{2\pi }$
Given, $\frac{h}{RC}$
where, $\text{RC = time constant}$
So,
$\frac{h}{RC}=\frac{L}{t}\Rightarrow \frac{\Delta L}{\Delta t}=\text{torque}$
