1. A particle has charge q = 0.100 C and mass m 100 grams. It is first accelerated from rest through a potential difference of 200 V and then it passes undeflected through a velocity selector consisting of perpendicular electric and magnetic fields. The electric field in the velocity selector is 100 V/m. What is the magnetic field in the velocity selector (in T)? (A) 2.00 (B) 0.750 (C) 3.50 (D) 4.30 (E) 5.00 (F) 6.00
