Can a massless string have different tension?

No. You really need some guidance here. Having A massless pulley doesn’t means that the tension in the string is equal everywhere.

Is tension in string same at all points?

Usually the rope is so light compared to the blocks that we can neglect the change in tension along it entirely, so the tension is the same at every point.

Why does a massless string have the same tension throughout?

The force equation will be T2-T1=Δma where ‘a’ is the acceleration of the tiny bit of the string . Now since Δm=0 ∴ T2=T1 i.e tension on either side of any arbitrary mass of the string is zero.In other words tension throughout the string is constant.

Can a string have different tensions?

The tension on the other side is therefore lower, since the pulley “helps” so this side does not carry the whole weight alone. Also, if the rope is not rigid (if it is an elastic rubber band e.g.), you will feel different tension in the rope when adding a load in one end over a pully as long as stretching happens.

Why are tension forces equal?

What is Tension Force Equal to? The system has a constant velocity and there is an equilibrium because the tension in the cable/string, which is pulling up the object, is equal to the weight force, i.e. mg. where m is a mass and g is the acceleration caused by the gravity which is pulling down the object.

Does mass affect tension?

If you increase the mass of the object (therefor its weight), you will increase its tension.

Is the tension in the string greater than?

the weight force (W) , of the ball, is in the downward direction, The net force on the ball is, T−W=F⟹T=W+F T − W = F ⟹ T = W + F . Thus, the tension in the string is greater than the ball’s weight.

How does tension act in a string?

The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.
