    A wide bottom cylindrical massless plastic container of height $9 \,cm$ has $40$ identical coins inside it and is floating on water with $3 \,cm$ inside the water. If we start putting more of such coins on its lid, it is observed that after $N$ coins are put, its equilibrium changes from stable to unstable. Equilibrium in floating is stable if the geometric centre of the submerged portion is above the centre of the mass of the object). The value of $N$ is closed to

    $Assertion :$ The pressure of water reduces when it flows from a narrow pipe to a wider pipe.
    $Reason :$ Since for wider pipe area is large, so flow of speed is small and pressure also reduces proportionately.
