3hey akand for the first qn it is 0 degree.Becos the given situation satisfies the minimum deviation position and so the ray shud be "parallel" to the base of the prism

1one more stupid question...........IF THE NUMBER OF STUPID QUESTIONS ARE MORE THAN ENOUGH AND U R FRUSTRATED THEN PLEASE DO LET ME KNOW..........ill stop them hehe
Va-Vb=10 volt,Kinetic energy of2C negative charge is taken from A to B ...........
a)increase by 20J
b)decrease by 5J
c)decreases by 20J
d)increase by 5J
1a better conceptual one.........
An uncharged insulated conductor A is brought near a charged insulated conductor B . what happens to charge and potential of B ?Why?

1for ur third question ans is C??
use refraction at curved surface distinctly for each side of the lens....
1wel yes.......iiturcomin........its correct.........they also asked if it was anticlockwise or clockwise...........
1
wel wat is its name????
a....2-amino toluene
b...2-amino methyl benzene
c...2-methyl aniline
d...2-methyl benzenamine
e...one of these
f....i dunno
1sky.......this was a doubt......i dont kno d answers........plzz explain urself.........i thought it shud be a or b.......but y c??? explain naa
1and mathi.........y only c??? i think all are correct.........coz i made this question hehehe
1explanation to ur 3rd question:
see refraction at first lens surface:
μ1/v - μ2/u = (μ1 - μ2)/R
=> μ1 /v = (μ1 - μ2)/R
=> v = (μ1 - μ2)/ μ1R
but μ1 < μ2 (tumne kaha)
so v is on the left of this surface.
now,
consider second surface .. (hopefully lens is thin !)
in the same way write the eqn..
finally we'll get: μ3 /v = (μ3 - μ2) /R
=> v = (μ3 - μ2) / μ3R
but μ3 < μ2
so agn v is to the left of this surface..
so we can see..
both the surfaces are acting as diverging surfaces...
so we get two divergent rays... hence ans is C.
(uff ! itnaa likhi :P ans C ba hua toh bahut zaada sad ho jaungi :( ) :P
3IUPAC name is 2 amino toluene and the common name is o-toluidine so a and e
1but sky lets use logic..........the light rays are coming from a denser medium to a rarer medium .........so they will converge....and they will converge twice..........so according to our senses(without using math or phy)....i think it shud be.........convergence with one ray..........I DUNNO......but thts wat logic says
1hey sanky......nice pic..........but in d organic ques......i think all are rite....i dunno
1denser -> rarer so converge???? !~#@!#$!$!!!!!!!!!
i dunno wat u are ssaying akand ... am sry dear [2]
@sankara..
there are few rays which are paraxial ...
others will gv distorted images... so y bother ...
1wel sky.......i hav done an expt called glass slab..........and i also kno tht convex lens is a converging lens......so i used both d concepts......hehe but y bother?? u already got a pink...
1baaaaaaaaaaap re!!
copy me hi kitna mushkil se banayi yaar !! yaha pe kaise banau [11]
i am really sorry [2] [2] [2]
