  1. 4 N
  2. 8 N
  3. 10 N
  4. 2 N

A
2 N
B
8 N
C
4 N
D
10 N
Solution
Verified by Toppr

Net force on the system(m1+m2=3kg) is F=12N so the common acceleration will be a=F3kg=4m/s2

Q5

Three blocks of mass M1, M2 & M3 are connected by massless strings as shown on a frictionless table. Where T1 is the tension in the string between block M1 and M2, T2 is the tension in the string between block M2 and M3. They're pulled with a force F=40N. If M1=10 kg, M2= 6 kg and M3 = 4 kg, then tension T2 will be:
