Question

ksaimouli · Answer

In the diagram above, a 1.0–kg cart and a 2.0–kg cart are connected by a rope. The spring scale reads 10 N. What is the tension in the rope connecting the two carts? Neglect any friction.
30 N
10 N
6.7 N
5.0 N
3.3 N

anonymous · Answer

As a guess, 10N is being applied on the 3kg system- intuition says 10/3 N is being exerted on the 1kg object to achieve the acceleration, so the tension is 10/3N. Probably incorrect as I didn't include the 2kg mass.

ujjwal · Answer

Divide total force into 3 parts (which will give you 3 parts of 3.3 N).. 2 parts pull 2 kg and 1 part pull 1 kg..
2 parts of 3.3N (total 6.6N) pulls 2 kg.. So, beyond it force applied (on 1 kg via rope)= remaining force=3.3 N which will be the tension in rope..
So, tension= 3.3 N
