they are vectors sir....and i think ans should be d
If axb=c
bxc=a
then find relation b/w a,b,c
I have got some ans..but i dont have answer key..so tell me ur answer.....

(a-c) x b = (c-a)
but we know that (a-c)xb is perpendicular to a-c vector.. so c-a = 0
Is this what you got?
but b is a vector..
how can it be equal to a scalar?
and you must have been tempted to say -1 not 1 ;)
sorry..my comment got deleted accidnetly..
"So are u geting b=1 ?? ""
but sir in options are
a)a=1,b=c
b)c=1,a=1
c)b=2,c=2a
d)b=1,c=a
are these vecots a, b, c or scalars!!
if they are scalars then the answer will be b (c=1=a)
I Mean yeah after seeing the options, the obvious thing is that these are scalars and not vectors..
so the correct answer is option (b)
eureka.. if they are vectors.. then the only option is a-c is zero..
otherwise a=1 makes it a scalar..
hence the answer will be that the question is wrong :D
oh yes....forgot that cross procuct....so silly [3][3]
so answer is just b=c
thanx [1][1]
