A disc of mass 50 kg rotates freely about a fixed horizontal axis through its centre. A thin cotton pad fixed to its rim can absorb water. Water drips onto the pad at the rate of 25 grams per sec, falling along a line passing through the horizontal axis. The angular velocity of the disc will get reduced to one fourth of its initial value time ____x10^(3) s.
