Hi....

Acording to a book it is given that the energy of the comp.cyclohexane is less than benzene indicating that cyclohexane is more stable than benzene.....how come it is this way.........

hi.......

It is given in m&b pg 574

hi...

force(F)=charge(q)*Electric (E)field..............

Hence,

F=qE

=8*10^--5 (3000i-600j)=24*10^--2i-4.8*10^-2j.please calculate

since F=ma......a=qE/m.....find a..then substitute in s=ut+.5at^2...fin the time taken for it to accelerate.......

if you are not able to under stand the explanation ....please do ask

Hi!...

Is it true that resonance and hyper conjugation are given same preference for stability?

hi.....

moreover only odd powers can be used since if it is even .... it woud be positive always and would never return to equilibrium position......

hi.

the halo.this gives possibilities of many isomers hence not prefferred...guess.. right?

hey.

indian..i didnt mean to hurt ..i thought you were a little worried about the question ......sorry anyway.............hope you do get through a good iit.....

hi.

it is ok indian......you might have done others well..........

all the b es t

hi........

Yes because p=a(coskt i - sinkt j)...f=dp/dt=a (-sinkt i-cos kt j).... the cross product would be zero. hence one way to get 90 degrees as the option

Hi...

that should be right....both correct ....but not the correct explanation

hey then no solution?

by the way what is the answer............

hey.

that should be the answer.....yeah.

HI............ if the coloumbs law ( say coloumb comes from heaven and asks for a change)was f+k(q1+q2)^2/r^2 can super position be used

Oh. well yes .......and in case the law was the second one.............

Wishin all the GO IITIANS ALL THE BEST

Hey..

why did f=Kq1*q2/ r^2 come.......why not K(q1+q2)^2/r^2...........then will super position be possible to apply............

hey...

thanks for replying.

but is there a criteria like only in presence of.....

by the way there was a question ..suppose if coloumb's law was

f=(Q+q)^2 /r^2.....dimensionally correct.super position principl e possible to apply

he........sorry

?Hey. my post isn't apppearing?
