A small sphere of radius $'r'$ falls from rest in a viscous liquid. As a result, heat is produced due to viscous force. The rate of production of heat when the sphere attains its terminal velocity, is proportional to
An electron of mass $m$ with an initial velocity $\vec{V} = V_0 \hat{i} (V_0 > 0)$ enters an electric field $\vec{E} = - E_0 \hat{i} (E_0 = \text{constant } > 0)$ at $t = 0$. If $\lambda_o$ is its de-Broglie wavelength initially,. then its de-Broglie wavelength at time $t$ is
An electron falls from rest through a vertical distance $h$ in a uniform and vertically upward directed electric field $E$. The direction of electrio field is now reversed, keeping its magnitude the same. A proton is allowed to fall from rest in it through the same vertical distance $h$. The time of fall of the electron, in comparison to the time of fall of the proton is
