### Physics Question: Modeling Central Forces**Question 10**: Can the following be reasonably modeled as a central force with constant radius \( r \)? Answer Yes or No.a. A ball on a string is swung in a horizontal circle.b. A ball on a string is swung in a vertical circle.c. A satellite orbits the Earth.d. A satellite spirals into a black hole.e. A car makes a U-turn at constant speed.f. A child rides on a merry-go-round.g. An ant rides on a slowing turntable.### Diagram Explanation:The image contains two diagrams. The first appears to be a circle with several equally spaced radial lines extending outward, possibly illustrating uniform circular motion. The second diagram looks like a smaller circle with an arrow indicating direction, possibly showing rotational motion or the effect of radial forces. ### Instructions for Students:- Assess each scenario to determine if it involves a central force acting with a constant radius.- Consider the effects of gravity, tension, and other forces in each scenario.- Reflect on how changes in velocity or trajectory influence the constancy of the radius.

a) The motion can be modeled as central force with constant r. yes. b)The motion can be modeled as central force with constant r. yes. c) The motion of satellite around the earth is not a circular rather it is elliptical. No d) The spiral motion changes the radius . No e) The curve can be considered as a circle. Yes. f) the radius of merry-go-round is constant. Yes g) yes.
