Question

A light spring balance S is attached to two bodies
of masses M=6 kg and m= 4kg. Forces F= 20 N
and f = 10N are applied to the masses as shown.
The spring balance, in steady state, reads
(1) 10 N
(2) 20N
(3) 6N
(4) 14 N
​

Answer 1

Answer:

• convert the spring system into massless rope system
• now the tension in the rope will be the reading of spring balance
• acceleration of both blocks will be as they are moving together

see the attachments!!..

your answer is 14N

Good luck ♧♧

hey ..are my anwers are wrong??
