DEAR RISHABH VATS,
IN THE GIVEN QUESTION THEY DIDNT MENTION ABOUT THE FRAME IN WHICH THE BODY IS PRESENT BUT TOLD THAT THE BODY IS AT REST SO DEFINIETELY BY APPLICALION OF NEWTON LAW OF MOTION ONLY WE FIND NORMAL REACTION AND mg BUT NO OTHER FORCE,SO DEFINITELY THE RESULTANT FORCE ON PARTICLE OS 0 SINCE THERE IS NO OTHER FORCES OTHER THAN N AND mg . SO THE ANSWER BECOMES THE FRAME MAY BE INERTIAL OR NON INERTIAL BUT THE RESULTANT FORCE ON THE BODY IS 0.
THESE DAYS IIT HAS BECOME POPULAR ALL OVER INDIA.SO IIT IS NOT ONLY ABOUT PROBLEMS BUT ALSO ABOUT THE THINKING ABILITY OF THE STUDENT AND ALSO THE APPLICATION OF THE FORMULA I.E WHERE TO USE THE EXACT FORMULA.
THANK YOU,
PLEASE APPROVE

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.
