Question

Object of masses 2kg and 4kg are sunspendes to two ends of a stilling which passes through the pulley.initally this system is at rest calculation the accleration and the tension

Answer 1

accn = net force on system/ tot mass
=> a = (m2- m1)g/ m1+m2
=>a = 20/ 6 m/sec^2.
T - 20 = 2a
T = 2(10+a).
