An electron flies into a homogeneous magnetic field perpendicular to the force lines. The velocity of the electron is v = 4 × 107 m/s. The induction of the field is 10–3T. What is tangential acceleration of electron in the magnetic field –
A
7 × 1015 m/s2
B
7 × 1013 m/s2
C
7 × 1014 m/s2
D
None of these
Answer
None of these
Explanation
Solution
Velocity magnitude will not change as magnetic field does not work on charge.
