Question

Each of 150 identical blocks sitting on a frictionless surface is connected to the next block by a massless string. The first block is pulled with a force of 150 N .

What is the tension in the string connecting block 150 to block 149?
T150 to 149=______

Answer 1

The tension in the string connecting block 150 to block 149 is 150 N, due to the force applied to the first block being transmitted equally through the massless string.

Step-by-step explanation:

The tension in the string connecting block 150 to block 149 is the same as the force applied to the first block, assuming a frictionless surface and massless strings as provided in the question. Because there is no friction to counteract the pull and no additional forces acting between the blocks, the force is transmitted equally through the massless string to each block. Therefore, the tension in the string connecting block 150 to block 149 is 150 N.
