Answer

  1. The difference between the emf of a cell and potential difference across the ends of the cell is called lost volts.
Explanation:
When the battery is discharging, the terminals voltage of the battery is always $≤$ Emf of cell $[∵\text{r}>0]$
$\therefore$ There will always be a difference which is defined to be lost volt.

A heavy ring of mass m is clamped on the periphery of al light circular disc. A small particle having equal mass is clamped at the centre of the disc. The system is rotated in such a way that the centre moves in a circle of radius r with a uniform speed v. We conclude that an external force:
  1. $\frac{\text{mv}^2}{\text{r}}$ must be acting on the central particle.
  2. $\frac{2\text{mv}^2}{\text{r}}$ must be acting on the central particle.
  3. $\frac{2\text{mv}^2}{\text{r}}$ must be acting on the system.
  4. $\frac{2\text{mv}^2}{\text{r}}$ must be acting on the ring.
