A velocity selector has an electric field of magnitude 2500 N/C,directed vertically upward, and a horizontal magnetic field that is directed south. Charged particles, traveling east at a speed of7.27 x 103 m/s, enter the velocity selector and are ableto pass completely through without being deflected. When adifferent particle with an electric charge of +4.40 x10-12 C enters the velocity selector traveling east, thenet force (due to the electric and magnetic fields) acting on it is2.17x10-9 N, pointing directly upward. What is thespeed of this particle?
