Thanks 4 the link!!....

and btw i too like the theory of relativity very much!...it's a different thing dat i dont understand much of it[3]

this is damn interesting field
relativity just amazes any science lover

i know this is TARGET IIT
but i saw a picture which i would like to share it upon einstein and another genius

do watch it if u have spare time

here's the link

Anyways...let it be!

I was reading some other chapter...i jsut came across this ques...found interesting so posted it...

I dunno much abt relativity...!!

@Aditya
it has to be mentioned in the question that the particle is traveling with the speed of light
then only ur answer makes sense

by the way
H.C Verma didn't mentioned because it was 4m that that chapter only
so it is understood

Aditya in #8
u mentioned

Mass is not variable!!...

so wats ur point!!!!!!!!!!!

relativity mein mass mein farak padta hai shayad
actually its a completely different story

And it is from Last chapter of HCV 2....

So, i think due to relativistic effect mass might be increasing and so the answer.

I just wanted to know the m in F=ma, is rest mass or something else?

Guys

Actually this is from HC Verma.....

He has given the answer to be b!

So, posted it

c

Philip Calvert ·

then definitely it is C aditya

11
Mani Pal Singh ·

if mass is constant then u can see
F=ma

so if mass is constant
so acceleration have to be constant

so wats the problem??

Aditya ·

Mass is not variable!!...

11
Mani Pal Singh ·

the thing that we have to keep in mind is

F=dp/dt
f=mdv/t+dm/dtv

so it all depends upon that the syatem is changing mass or not

i hope now u can fill the options[1]
