Transcribed Image Text:(a) An alpha-particle (m = 6.64 x 10-27 kg, q=3.2 x 10-¹9 C) moving with a velocity
v = (2.0i - 4.0k) x 106m/s enters a region where E = (5.0î - 2.0ĵ) × 10¹V/m
and B* = (1.0î + 4.0k) × 10-²T. What is the initial force on it?
(b) An electron moving with a velocity v = (4.0 + 3.0f + 2.0k) x 106m/s enters a
region where there is a uniform electric field and a uniform magnetic field. The
magnetic field is given by B* = (1.0î - 2.0ĵ+ 4.0k) × 10-²T. If the electron travels
through a region without being deflected, what is the electric field?
