[QUOTE="stumpoman, post: 4506333, member: 456658"] [h2]Homework Statement [/h2] I have a question about notation. My professor posted an older practice test with some different notation techniques than I am used to. "[U]Sphere Charge[/U] Find the electric field 2.5 m from the center of a region of space with a charge density given by ro=5.5 E-15 R**(2.3)" I understand most of it but am unsure what the R**(2.3) means. [h2]Homework Equations[/h2] E = kQ/r^2 ρ = 5.5 E-15 [h2]The Attempt at a Solution[/h2] I assume the R**(2.3) has something to do with the volume of the sphere but other than that I have nothing. Attached is a screenshot of the question. [/QUOTE]
