JEE 2008

ST.1 AN ASTRONAUT IN AN ORBTING SPACE STATION ABOVE THE EARTH EXPERIENCES WEIGHTLESSNESS

ST.II AN OBJCECT MOVING AROUND THE EARTH IS IN A STATE OF FREE FALL.

ACC. TO ME THE ST.II IS NOT A CORRE CT REASON FOR THE ASSERTION AS WE FEEL WEIGHTLESSNESS IN A SPACE SHUTTLE BEACAUSE OF THE ABSENCE OF A NORMAL FORCE ON THE BODY

i feel both statements r true and st2 supports the 1st

the astronaut experiences a centrifugal force uqual to the gravitational force of attraction and hence its like a free fall.

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.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
