Aieee

remember hydrostatic pressure is also a scalar due to same reason

subash s agree with u i also thought the same

but a queation is largely

VAGUE

time has a unique direction.... past → future....so 2 is right

read the question

Time has a direction, it can never be negative still it is a scalar and not a vector quantity. Which statement is the correct explantion for the time not being a vector?

how does having a unique direction explain that time is not a vector???

ohhh....sorry machan.......messed up

k.. then dis might be lik dis..

a vector in a plane is said to ve direction throughout d plane.. but time has a unique direction....

naturally It is not obeying law of parallelogram addition...

so it cannot be a vector...

ellam appa appa thonum..!!!!

Anirudh: i think that it is not a vector bcos it has a UNIQUE direction
other vectors can be made to have different directions
like E, B, F,....
me: but take the examples like dipole moment,
area vector
they also have unique directions
Anirudh: look
me: yes looking
Anirudh: x axis as time axis
me: yes
Anirudh: the value goes from 0 to infinity
me: yup
Anirudh: take another plane (with time not on x axis)
me: then
Anirudh: place two charges one at (-a,0) and the other (0,a)
me: why are you bringing in charge
Anirudh: let the charges be at (-a,0) and (a,0)
me: equal charges?
Anirudh: dei, sorry da
ie hanged
me: oh
Anirudh: ok....solution continues
me: k
Anirudh: took the charges??
me: ii asked whether equal or not>

Anirudh: equal da
ok?
me: k
Anirudh: so dipole moment points in the direction +i
right?
me: k
rite
Anirudh: ok then
me: then?
Anirudh: Now consider -q at (-1,1,)
sorry
(-1,-1)
and place +q at (1,1)
me: k i think im getting what you are coming to say
Anirudh: so dipole now points in the direction
i+j
so u ssee?? direction is not unique
me: similarly in the case of time take the axis in the direction of j then?
Anirudh: no
this is enough to prove that direction of dipole is not unique
:)
understood the solution?
any arguements?
me: no for now

dipole moment has diff directions

up down left right how can u say it has unique direction?

But Celestine I was talking about it in the sense that it is always directed from negative to positive.

This is the case with time also past →future

Isnt there an analogy there?

Even i think ans should be 'a' coz the fact dat it has a unik dirⁿ doesn't explain dat it's a scalar...!!

Even current has a unik dirⁿ but it's a scalar coz it doesn't obey law of ll^m of vectors!

I dunno y the ans is c

sorry da machan idon't have clr idea
