A charged particle having a charge of 2x10^-9 and mass 8.3x10^-17 goes undeflected when passing through perpendicular electric field E (7.5x10^3 V/m) and magnetic field B (0.25 T).
1) What is the speed of the charged particle?
2) When the electric field is turned off, the charged particle moves in a circle. What is the radius of the circle?
