The question paper II - Physics, Chemistry and Mathematics - of ISAT for admission in IIST or Indian Institute of Space Science and Technology is as follows:

An ideal gas undergoes two successive processes A and B. In the process A, the values of the increase ∆U in internal energy and the work W done by the gas are ∆U= 72J and W=-72J, respectively. For the process B, ∆U=0.
(a) Process A is adiabatic, process B is isochoric
(b) Process A is adiabatic, process B is isothermal
(c) Process A is isothermal, process B is adiabatic
(d) Process A is isobaric, process B is adiabatic

The pseudoforce on the object as seen from the box frame is
(a) 2mg upwards
(b) 2mg downwards
(c) 2Mg downwards
(d) 2Mg upwards

The net force (pseudoforce + all real forces) on the object as seen from the box frame is
(a) mg downwards
(b) 2mg downwards
(c) 0
(d) mg upwards

Now the robot releases the object. It will hit
(a) CD in time square root of 2H/g
