An ion, stripped of a single electron, enters the magnetic field B of a mass spectrometer with a velocity v as shown.  It hits the detector a distance 2r from place where it enters the B-field.  The direction of the B-field is into the page.  Which is/are all the change(s) that INCREASE the distance travelled by the ion from the place where it enters the B-field to where it hits the detector?

Earth orbits the sun at a distance of roughly 1 AU (astronomical unit) and receives 1.75 x 1017 W of power.  Saturn orbits at roughly 10 AU and has a radius 9 times of Earth’s.  What is the approximate solar power delivered to Saturn?  (The area of a sphere is 4πr2 and the area of a circle is πr2.)
