Three blocks of masses 2 kg, 3 kg and 5 kg are connected to each other with light string and are then placed on a frictionless surface as shown in the figure. The system is pulled by a force F = 10 N, then tension T1 is :

a
1 N
b
5N
c
8N
d
10N

detailed solution

Correct option is C

Acceleration =102+3+5=1m/s2,T1=(3+5)a=8×1=8N
