Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Nope
Ahmm yes
With respect to each other na
Yes
But acceleration ki baat kar raha na
Velocity necessarily zero honi chahiye?
um agar dono frame se same acceleration dikh raha hai particle ka to dono frame ka acceleration to zero hona hi cheye with respect to each other
Nahi dono frames ka aapas me same hai
Particle ka tabhi dono se same dikhega na
Apas me same hone se kya matlb hai
Dono frame ka ground frame se acc same hai aisa?
Yeah yeah that way
Jaise velocity same honi chahiye to appear on rest
Vaise hi acceleration same honi chahiye for the speed to appear to be increasing at the same rate
So a option seems correct then?
A will only be correct provided the frames move in same direction, idhar bas magnitude ka baat Kiya Hai
Khud soche dekho if a particle is at rest, one frame moves left with a=4, another moves right with a=4, both won't be at rest w.r.t each other
Direction could be different na
As @coolguy. said

Hona to chauye
Yeah this makes sense
But the answer is D
Can you explain d option as well?
Again when they move in opposite directions
That's when max relative accn is 8
Minimum is zero when they move in same dirn
Understood
Thanks a lot
Np :)
What about option b? Moving but with zero acc wrt each other
That is incorrect
Wait
yea
I mean they can be accelerating w.r.t to each other right
We just saw that it can range from 0 to 8
The relative accn
So yeah
The statement says they must not accelerate w.r.t each other
That's wrong
I see
Thannx
Yep
