Is the pulley massless and frictionless? That's the key.I have attached a pic with my question. I want to know if T1>T2 or not.
Careful! That's not true. In general you'll have to solve for the tension in the string by applying Newton's 2nd law.As much as I know, Tension in a string = Earth's Gravitational force.
I don't know what you mean. T1 and T2 are tensions. Regardless of the size of the mass on the ends of the string segment, the tension on both sides of a massless and frictionless pulley will be the same.T1 has a mass greater than T2.
Only if the string is also of negligible massAgree completely with DocAl and will add that the tension in a string is the same everywher.... all the way along it.
