Answer: The correct answer is "center-seeking".
Explanation:
Centripetal force is the force which is required to keep the body in the circular motion. The direction of the centripetal force is towards center of the circle.
The expression for the centripetal force is as follows;
Here, r is the radius, v is the velocity and m is the mass of the object.
Without this force, the body cannot move in the circular motion. Then, it follows the straight line motion.
The direction of the centripetal force acting on a ball on a string being spun in a circle around a person is center-seeking.
Therefore, the correct option is (D).

The acceleration of an object given it's mass and the force acting on it can be found by using the formula
m is the mass
f is the force
From the question we have
We have the final answer as
<h3>10 m/s²</h3>Hope this helps you
The magnitude of the force that the beam exerts on the hi.nge will be,261.12N.
To find the answer, we need to know about the tension.
<h3>How to find the magnitude of the force that the beam exerts on the hi.nge?</h3>- Let's draw the free body diagram of the system using the given data.
- From the diagram, we have to find the magnitude of the force that the beam exerts on the hi.nge.
- For that, it is given that the horizontal component of force is equal to the 86.62N, which is same as that of the horizontal component of normal reaction that exerts by the beam on the hi.nge.
- We have to find the vertical component of normal reaction that exerts by the beam on the hi.nge. For this, we have to equate the total force in the vertical direction.
- To find Ny, we need to find the tension T.
- For this, we can equate the net horizontal force.
- Thus, the vertical component of normal reaction that exerts by the beam on the hi.nge become,
- Thus, the magnitude of the force that the beam exerts on the hi.nge will be,
Thus, we can conclude that, the magnitude of the force that the beam exerts on the hi.nge is 261.12N.
