Which would cause the greatest increase in the acceleration of a satellite?

A decrease in the radius and an increase in the tangential speed

Explanation:

As we know that in circular motion the acceleration towards the center of the circular path is given by the formula

now we can say that in order to increase the acceleration of the circular motion we can change the value of speed v and radius R both

here we know that

v = tangential speed

R = radius of path

so here since speed is directly dependent on the acceleration while radius is inversely depends on the acceleration so correct answer must be

A decrease in the radius and an increase in the tangential speed
