At the instant $t = 0,$ a force $F = k t$ ( $k$ is a constant) acts on a small body of mass $m$ resting on a smooth horizontal surface. The time, when the body leaves the surface is

Options:

Answer:

Solution:

$N + F \sin α = m g$

The body leaves the surface when the normal reaction on it becomes zero.

$N = 0$

$\Rightarrow k t \sin α = m g$

$t = \frac{m g}{k \sin α}$
