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

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

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

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

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