Hello hope you're doing well
I'm having a great problem understanding Newton's third law
let's say that we have 2 bodies with masses m1 & m2 where m1>m2
the 2 bodies are connected with a rope body1________body2----->F
a force F is applied on body 2 as shown below
body1________body2----->F
friction is ignored
how does the 2 bodies move when the rope is massless and when it mass can't be ignored
there is none
according to Newton third law
when b2 aplies a force on the rope, the rope aplies a force on b2 so that it is equal to F in the opposite direction F2
and the rope aplies a force on b1 in the same direction as F let's call it F3
and b1 aplies a force on the rope equal to F in the oppsite direction let's call it f4
F4<---body1--->F3________<---F2 body2--->F
so there are 2 forces on B2 "F" and "F2" which are identical how will it move ?
body 1 has only 1 force acting on it "F3" so I guess it will move toward Body 2
also what's the diffrence when the rope has a mass and when it is massless
in short I'm stuck

The Attempt at a Solution
according to Newton third law
when b2 aplies a force on the rope, the rope aplies a force on b2 so that it is equal to F in the opposite direction F2
and the rope aplies a force on b1 in the same direction as F let's call it F3
and b1 aplies a force on the rope equal to F in the oppsite direction let's call it f4
