# Tension of a String between two objects (horizontal, no gravity or accelleration?)

1. The problem statement, all variables and given/known data
Two blocks of masses 2kg (a) and 3kg (b) rest on a smooth horizontal surface and are connected by a taut string of negligible mass. A force of 10 N is applied to the 3kg mass as shown in figure (below). Calculate the tension in the string between them.

2. Relevant equations
Friction has not been discussed yet, it is in the next chapter.

3. The attempt at a solution
I can figure out how to calculate the tension on a string of a pulley or the tension of a string with a hanging object attached... but because there is no gravity to work out I dont know how to calculate this?

Any help is appreciated!!!

Write out Newton's second law for both masses.

You should also reexamine the part of your subject line that says that there is no acceleration.
