P. 3811. A charged particle travels into a region in which there is a friction force proportional to the particle's velocity. It travels 10 cm from the point of entry into the region before coming to rest. If a magnetic field of unknown strength is turned on in the region, the particle comes to rest at 6 cm from the point of entry. How far from the point of entry will the particle come to rest if the magnetic field is doubled?
