Question

Three block are connected as shown, on a horizontal
frictionless table and pulled to the right with a force
T3 = 60 N. If m1 = 10 kg, m2 = 20 kg and m3 = 30 kg,
the tension T2 is-

(A) 10 N
(C) 30 N
(B) 20 N
(D) 60 N

Figure attached for reference


pls answer this question

pls ​

Answer 1

Answer:30N

Explanation:easy .........

60-T2=30a

T2‐T1=20a

T1 =10a then a=1m/s^2

T2=30
