SUMMARY
The tension in a string between two blocks of equal mass, subjected to a pulling force of 17 Newtons, can be calculated using Newton's Second Law. By analyzing the forces acting on each block through free body diagrams (FBDs), it is established that the tension (T) equals half of the pulling force when both blocks accelerate uniformly. Therefore, the correct answer is 8.5 Newtons. This conclusion is derived from the equations F = ma, where the net force acting on each block is balanced by the tension in the string.
