Question

three identical blocks are pulled on a horizontal frictionless surface. if the tension in the rope held by the habd is 30N what is the tension in the other ropes?
they would vary in the ratio of the mass that is being pulled by the string.
Since the surface is frictionless, all the blocks would accelerate in a similar manner, that is, they have the same value of acceleration.
So if the string attached to block 3 is pulled by 30N,
acceleration= 30/(3m)=10/(m); where, 'm' is the mass of each block.
tension on string pulling block 2 = 2m*(10/m)=20N
tension on string pulling block 1= 1m*(10/m)= 10N
