Question
Two blocks of masses 2 kg and 4 kg are hanging with the help of massless string passing over an ideal pulley inside an elevator. The elevator is moving upward with an acceleration g/2. The tension in the string connected between the blocks will be
Joshi sir comment
equation 1
4g+4g/2-T = 4a
equation 2
T-2g-2g/2 = 2a
now solve
