Answer:
Equal to the weight of the object
Explanation:
There are two forces acting on the object hanging on the string:
- The tension in the string, T, acting upward
- The weight of the object, mg, acting downward
We can write Newton's second law as:
[tex]T-mg=ma[/tex]
where a is the acceleration of the object.
Here we are told that the elevator is moving at constant speed: this means that the acceleration of the object is zero, therefore a = 0 and the equation becomes
[tex]T=mg[/tex]
therefore, the tension in the string is equal to the weight of the object.
