How to find Tension between two boxes

  1. Apr 5, 2012 #1
    A string is attached between two boxes with equal masses of 5kg EACH. The boxes are being pulled with a force of 30N and the acceleration is 3m/s^2.


    I think T=ma. But does 'm' mean I have to add both masses?

    T=10x3
    =30N.

    I'm desperate to know if this is right or wrong. Thanks a million!!! Pleease answer asap!!! :)

    and what do u mean by T...the tension in the string?

    i think the tension(T) will be 15N
    for 1 st box
    eq will be 30-T =5(3)
    and for second T=5(3)

    Yes T is tension.
