WBJEE 2008 (contd)

Hey everybody,
I would like to thank a couple of people for bringing to our notice two mistakes in our solutions to the physics paper of WBJEE 2008. Here are the correct solutions to those two questions:

31. The radius of curvature of a concave mirror is 24 cm and the image is magnified by 1.5 times. The object distance is: (a) 20 cm

37. A silicon and a germanium diode has identical physical dimensions. The band gap in silicon is larger that that in germanium. An identical reverse bias is applied across the diodes. (c) The reverse currents are identical in the two diodes


We also regret not having been able to upload the solutions to the mathematics and chemistry papers. This has been due to a very busy schedule we've been subjected to. Though, we are happy that we were the first ones to upload the physics solutions.


Here is a link to solutions of all the papers of WBJEE 2008 as given by a coaching institute: Aakash
BIOLOGY
PHYSICS AND CHEMISTRY
MATHEMATICS


Hope these prove to be useful. If you face any doubt regarding any question in the papers, you are free to discuss with us in this forum.
