first clear ur concept from book HC Verma or Dc pandey choose any one ....
after solve numericals ....
BAYANA SAGAR
FRICTION:-The force opposed on any body which is in motion to reduce the motion is called friction.
There are three types of friction.they are:-
(1)Static friction(or)limiting friction.(fs)
(2)kinetic friction(or)dynamic friction.(fk)
(3)rolling friction.(fr)
fs=Us.N for further information type the question and mail to the address.

ITS SIMPLE
ALWAYS TAKE FRICTION IN OPPOSITE DIRECTION OF MOTION ,............ BUT IN CASE OF ROTATIONAL U WILL HV TO ANALYZE THE PROBLEM
EX: CAR MOVING IN +X AXIS DIRECTION FRITCTION FORCE WILL ALSO ACT IN SAME DIRECTION OF MOTION
TO UNDERSTAND THIS
CONSIDER
THE WHEELS OF CAR AND SEE TANGENTIAL VELOCITY ITS TOWARDS -VE X AXIS
FRICTIONAL FORCE IS GIVEN BY
COEFFICENT OF FRICITON*NORMAL FORCE IN ANY CASE..............
IN CASE OF INCLINATION RESOLVE FORCES IN X AND Y DIRECTIONS
U CAN REFER TO HC VERMA SURELY IT WILL MAKE UR BASIC CLEAR

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.
