How to find Tension between two boxes

[SailorMoon01]

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?

 

[babita]

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)

 

[SailorMoon01]

Yes T is tension.

k then I've wrote what i think

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