If an object travels at a constant speed in a circular path, the acceleration of the object is:

1- larger in magnitude the smaller the radius of the circle.

2- smaller in magnitude the smaller the radius of the circle.

3- in the same direction as the velocity of the object.

4- in the opposite direction of the velocity of the object.

5- zero.

1- The acceleration of the object is larger in magnitude the smaller the radius of the circle.

Explanation:

The acceleration of an object in a circular path is

As can be seen from the equation, if the radius of the circle is decreases, the magnitude of the acceleration increases.

As for the direction of the acceleration, it is always towards the center, and it is always perpendicular to the direction of the velocity.

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees.
