Calculate the acceleration of the mass 12 kg shown in the setup of fig. Also calculate the tension in the string connecting the 12 kg mass. The string is weightless and inextensible, the pulleys are weightless and frictionless-
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
12 g – 2T = 12a
T – 4g sin 30° = 4b
T – 4 sin 30° = 4(2a)
a = 
12 kg Tension in the string connected to 12 kg = T' = 2T =
