AP EAPCET 2025 - 21st May Morning Shift | Laws of Motion Question 9 | Physics

As shown in the figure, a force $F$ is applied on a block of mass $\sqrt{3} \mathrm{~kg}$ placed on a rough horizontal surface. The maximum value of $F$ for the block not to move is (Coefficient of static friction between the block and the

surface is $\frac{1}{2 \sqrt{3}}$ and acceleration due to gravity $\left.=10 \mathrm{~ms}^{-2}\right)$

A balloon carrying some sand of mass $M$ is moving down with a constant acceleration $a_0$. The mass $m$ of sand to be removed, so that the balloon moves up with double the acceleration $a_0$ is

$m=\frac{2 M a_0}{a_0+g}$

$m=\frac{2 M a_0}{a_0-g}$

$m=\frac{3 M a_0}{g+2 a_0}$

$m=\frac{3 M a_0}{g-2 a_0}$

The acceleration of a body sliding down the inclined plane, having coefficient of friction $\mu$ is

$a=g(\sin \theta+\mu \cos \theta)$

$a=g(\cos \theta-\mu \sin \theta)$

$a=g(\sin \theta-\mu \cos \theta)$

$a=g(\cos \theta+\mu \sin \theta)$
