A plate of mass M is moved with constant velocity v against dust particles moving with velocity u in opposite direction as shown. The density of the dust is ρ and plate area is A. Find the force F required to keep the plate moving uniformly is Aρ(u + v)N, then N is :
    Correct answer is '2'. Can you explain this answer?
    Verified Answer
    A plate of massMis moved with constant velocityvagainst dust particles...
    Force F on plate = force exerted by dust particles
    = force on dust particles by the plate
    = rate of change of momentum of dust particles
    = mass of dust particles striking the plate per unit time × change in velocity of dust particles
    The correct answer is: 2
