One end of a wire is attached to a ceiling, and a solid brass ball is tied to the lower end. The tension in the wire is 160 N. What is the radius of the brass ball?

Well, the tension is from the brass ball, and you are given the weight as 160N.

Weight=densitybrass*g*(volume)

Figure volume, you will have to look up the density of brass. Then from the volume, you can determine the radius (volume= 4/3 PI r^3)
