If a Uranium-235, with a charge of 3.20 x10-19 C, passes through a uniform magnetic field of (1.9670x10^3) T at a perpendicular speed of (4.818x10^4) m/s, what is the radius (in m) of deflection of Uranium-235 in this magnetic field? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer Question 6 (1 point) Alpha particles travel undeflected through magnetic and electric fields that are perpendicular to each other. The speed of the alpha particles is (5.245x10^5) m/s and the strength of the magnetic field is (2.17x10^-1) T. What is the electric field strength? Note: Your answer is assumed to be reduced to the highest power possible.
