We know the circumference of a circle is => 2 * pi * R
thus,
C = 2pi * R
C/R = 2pi...................(1)
from eqn. it is revealed that 2pi is an angle thetha that is equal to 2pi.
thus it isvalid for all curcuference thus.
C/R = thetha
C = thetha * Radii.

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

the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
