Hi, thank you for posting your question here at Brainly.
When the object is at equilibrium and the object is just freely hanging from the cord, then the summation of forces along the y direction would just be the tension of the cord and the weight of the object. Since both forces are opposite in direction, at equilibrium, they are equal. Hence, in this case, the tension is also equal to 52 N.
The answer is a
Hope this helps!
