Question
Two blocks are connected by a massless string that passes over a massless pulley, as shown. In the absence of friction, how does the tension force exerted by the string on the 250 N block compare with the tension force exerted by the string on the 350 N block? The two forces are equal. The force on the 250 N block is smaller by a factor of 0.71. The force on the 250 N block is equal to the weight of the 350 N block. The force on the 250 N block is larger by a factor of 1.4. The force on the 250 N block is always equal to its weight.Explanation / Answer
In the case of a string pasing over a pulley , the forces acting on the string are caused by the weights attached to its two end points. Hence the tension is the collective efect of the attached weights. Which will be constant at any point of the string.
So answer is
The two forces are equal
