If a pulley is massless, does it have tension?

Solution

SOlution :

The main aim of the pulley is to change the direction of the tension. Pulley doesnt provide the tension.

SO coming to your question If a pulley is massless then the tension then the tension will purely depend on the masses attached at the end of the string.

And if the pulley is massless then you need not apply a non zero net torque to increase the angular acceleration.
