hai yaarrr iam vamsee.consider the case when lift is moving with uniform velocity downwards after some time it starts descending with an acc a=g/3.so we can write a1=g-g/3.t=2.22/7.squqre root ofl/a1.thereforeT=2.22/7.SUARE ROOT OFI/G-G/3.
IN THE OTHER CASE WHEN LIFT MOVING UNIFORMLY IN UPWARD DIRECTION AFTER COME TIME IT DESENDS WITH AN ACCELERATION G/3.THEN WE CAN WRITET=2.22/7SUARE ROOT OF L/G+G/3.......
IAM SORRY IF ANY MISTAKES ARE FOUND I TRIED MY LEVEL BEST YAAAR

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.
