The position vcctor r of a point p at time t satisfies the equation dr w x r, where is a constant non-zero vcctor. show that r is constant and that plies n a fixed plane deduce tht p describes a circle with constant speed 10.

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?
