5.Magnetism and Matter
medium
A short magnet is allowed to fall along the axis of a horizontal metallic ring. Starting from rest, the distance fallen by the magnet in one second may be.....$m$
A
$4$
B
$5$
C
$6$
D
$7$
Solution
(a) We know that in this case acceleration of falling magnet will be lesser than $g$. If $‘g’$ would have been acceleration, then distance covered $ = \frac{1}{2}g{t^2} = 5m$.
Now the distance covered will be less than $5\, m$. hence only option $(a)$ is correct.
