is tension force also an electromagnetic force? if it is, why is it so?

i dun think so...... coz if in a string u go to see the electromagnetic forces they r negligible....... tension is a pulling force.....its a purely mechanical force....if u dun mind can i ask u a question...??? wer did u find tat question.....????

i think that it is an electromagnetic force at a molecular level??

Let me tell u wat xactly is tension force at molecular level
When u pull a thread or a string, the distance between itz molecules tends to increase
This causes disturbance at the molecular level
So the molecules start attracting the neighbouring molecules to level the gap formd as a consequence of the force applied in the direction of the force
We term this intermolecular force at macroscopic level as tension, thatz it
Electromagnetism plays no role as far as i think
Correct if i m wrong
Rate if this helps u...

tension & electromagnetic force are two entirely different forces. tension is mostly in string where there is some kind of contact whereas electromagnetic forces are the force developed due to motion of charges (independent of contact of bodies)....
so, electromagnetic forces cannot be considered as tension...
i hope this helps....

yep buddy..its PURELY an electromagnetic force.........
electromagnetic forces b/w electrons n protons of string near lower n upper end produce resultant force preventing a directly attached body (like a block) to fall.....n this is tension....
u shud read:
hcv1 pg no.58 (the forces) right side para 2 frm above
rate me if found useful....

yes tension is a electromagnetic force (at molecular(atomic) level) .refer hc verma "forces " chpt.(vol 1) for more info

Yes, tension is a kind of electromagnetic force which acts betwn the electrons & protons of a stretched string. look up h.c. verma (vol 1)--forces.
