1. The problem statement, all variables and given/known data A long solenoid has 100 turns/cm and carries current i. An electron moves within the solenoid in a circle of radius 2.20 cm perpendicular to the solenoid axis. The speed of the electron is 0.048 c (c = speed of light). Find the current i in the solenoid. 2. Relevant equations i= mv/e*mu*n*r 3. The attempt at a solution i= (9.11E-31kg)(.0480)(3.0E8)/ (1.6E-10 C)(4*pi E-7 Tm/A)(100/.01 m) (2.2E-2) = .266 A this answer is wrong... what am i doing wrong? thank you!
