Two blocks, connected by a string, are accelerated to the right by a force applied to a second string.

The green block has mass M_green. The blue block has mass M_blue.

In which string is the tension larger?

1. The string between the blocks has a larger tension.
2. The string on the right has a larger tension.
3. The tension is the same in both strings.
4. The answer depends on the two masses.

Consider the free-body diagram shown for the blue block. Is it complete?

1. Yes
2. No (state what is missing if you choose this!)
