Hi, I learnt the basics about tensional force and I have some queries about it. I'm hoping you guys are able to clear out these doubts. When I have string connected to an object on one hand and the other is connected to me, when I exert a force which is too small in magnitude to move myself eg I pull with 10N and the string pulls back with 10N. But I thought the object also experiences a force of 10N, so why won't it move forward? Then when I raise my force to 15N such that now I have a net force of 5N I will thus start to move forward. However, I thought the object behind experience 10N of force too? So why is it able to move now unlike the previous scenario. I think my theory is quite wrong so I'm hoping you guys can help me out with this. Thanks!
