A particle of mass 1kg is moving along a straight line y=x+4. Both x and y are in metres. Velocity of the particle is 2m/s. Find the magnitude of angular momentum of the particle about the origin
Dear student,
Magnitude of angular momentum= mvr
m=1 kg
v=2 m/s
r=4 m
so L=8 kg m2/s

x-y+4 =0
perpendicular distance of this line from origin is given by
(x-y+4)/21/2 =4/21/2 = d
angulat momentam = mvd
=8/21/2 =4sqrt2 units
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
