Three blocks of masses m 1 , m 2 and m 3 are connected by massless strings as shown on a frictionless table. They are pulled with a force T 3 = 40 N. If m 1 = 10 kg, m 2 = 6 kg and m 3 = 4 kg, the tension T 2 will be-
Text Solution
Verified by ExpertsThe correct answer is:
D
Acceleration of system a = 
= 2
From FBD of block m 3
40 –T 2 = 4 × 2
T 2 =32 N
