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.

WBJEE 2008

WBJEE'08 which was scheduled to be held in April, due to reasons which are quite well-known, was shifter to 24th day of May'08 - that is today....

Students gave their exams amidst lots of speculations over what kind of subjective questions does the board plan to give....they did turn out to be tough - as the general opinion said. Though, they carried double the marks of their objective counterparts, thereby justifying their difficulty :)

Now, a quick analysis:
Physics was definitely the easiest of the lot. A more or less decent preparation would get one through with a very good score. Chemistry and Maths were almost on a similar platform. Though, certainly slightly tougher than Physics. Chemistry, in particular, had a good dose of organic chemistry and those who are comfortable with it, would have found it quite easy as well. Maths, as always, had a slight tinge of 'lengthiness' attached to it, but nothing which was not doable.

The deciding factor would almost certainly be Mathematics.


Here, I and my friend have provided the solution for the Physics paper (the objective section only). Due to paucity of time, as well as resources, we haven't yet come up with the other subjects' solution. But, we are trying our best.

We are, but humans (oh yes :D ). And hence, mistakes are indispensable. We would love to know if we made any mistakes in the solution. Also, because of lack of time, we have just given the answers (and not the solutions or the other options). If, you have any doubt as to how we reached a particular answer, you are free to contact us here. We'll try to reply you at the earliest :)
