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!!! :)

babita

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.
