Julie runs around the curve of a track in lane 1 while Monica runs around the curve in lane 8. The radius of lane 8 is twice as big as the radius of lane 1. If Julie has to run 50 m to get fully around the curve in lane 1, how far does Monica have to run to get fully around the curve in lane 8?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
