Three masses of 1 kg, 6 kg and 3 kg are connected to each other with threads and are placed on table as shown in figure. What is the acceleration with which the system is moving? Take g = 10m s -2 .
Text Solution
Verified by ExpertsThe correct answer is:
C
30 – T 2 = 3 a [Newton’s II law for 3 kg block] [3 kg]
T 2 – T 1 = 6 a [Newton’s II law for 6 kg block] [6 kg]
T 1 – 10 = 1 a [Newton’s II law for 1 kg block] [1 kg]
By adding three equations
30 – 10 = 10 a
a = 2 m/s 2 .
