A box is placed on the platform of a spring balance which is adjusted to zero when the box is empty. A continuous stream of pebbles, each of mass 0.2 gm and negligible volume, is then poured into the box from a height of 20 m above its bottom at a constant rate of 1000 pebbles per second. The collision between the box and the pebbles is perfectly inelastic and the velocity of the box is negligible. The scale reading (in N), 2sec after the pebbles begin to fill the box is
