How to find Tension between two boxes

  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?


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

  3. and what do u mean by T...the tension in the string?
  4. 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)
  5. Yes T is tension.
  6. Thank you so much :)
  7. k then i've wrote what i think
  8. welcome :)
