Each of 100 identical blocks sitting in a frictionless surface is connected to the next block by a massless string. The first block is pulled with a force 100 N.
a) what is the tension in the string connecting block 100 to block 99
B) what is the tension in the string connecting block 50 to 51?
I don't know how to do this. The only equation I got was T2-T1=ma for box 99 where T2 is the tension string attaching to box 98 and T1 is the tension in the string attached to 100. Also for box 100 I got -T=ma and plugged this into the equation -100 + T=ma and got T=50 N but this is wrong for part A and is supposed
To be the answer for part B but I don't see why. Can you please explain how to do this?
