Current Question (ID: 16996)

Question:

$\text{A short magnet is allowed to fall along the axis of a horizontal metallic ring.}$ $\text{Starting from rest, the distance fallen by the magnet in one second may be:}$

Options:

1. $4 \text{ m}$
2. $5 \text{ m}$
3. $6 \text{ m}$
4. $7 \text{ m}$

Solution:

$\text{When there is no horizontal ring below the magnet, the distance covered by}$ $\text{the magnet} = \frac{1}{2} gt^2 = \frac{1}{2} \times 10 \times 1 = 5 \text{ m}$ $\text{When there is a horizontal ring below the magnet, the acceleration of the}$ $\text{magnet} < g \text{ and the distance covered by the magnet} < 5 \text{ m.}$
