An Electric Field and a Magnetic Field Are at Right

question 30

Multiple Choice

An electric field and a magnetic field are at right angles to each other and to the direction of a beam of electrons. There is no deflection of the beam when the magnitudes of the fields are 30 *10⁴ V/m and 2.0 *10^-3 T, respectively. The velocity of the electrons must be approximately

• A) 0.60 km/s
• B) 6.7 * 10^-8 m/s
• C) 2.3 * 10¹⁶ m/s
• D) 1.5 * 10⁸ m/s
• E) 1.5* 10^-8 m/s
