Question

As shown in figure a block of mass m is attached with a cart. If the coefficient of static friction between the surface of cart and block is µ than what would be accelcration a of cart to prevent the falling of block ?

$a > \frac{m g}{m}$
$a > \frac{g}{m}$
a ≥ g
a<g

The correct answer is: a ≥ g
