how to solve this question with figure 3 blocks r connected
together like on a horizontal frictionless table pulled to right
with a force=50n if m1=5kg, m2=10kg, m3=15kg find tension t1 and
t2
2 two masses of 7kg and 12kg r connectd at two end of light
inextinsible string that goes over frictionless pulley find
acceleration of mass and tension on the string
