A particle of mass 
comes down on a smooth inclined plane from point 
at a height of 
from rest. The magnitude of change in momentum of the particle between position 
( just before arriving on horizontal surface)and 
(assuming the angle of inclination of the plane as 
with respect to the horizontal) is
