Magnetic field due to currentHard
Question
An electron moving with a velocity 
= 2î m/s at a point in a magnetic field experiences a force 
= - 2î N. If the electron is moving with a velocity 
m/s at the same point, it experiences a force 
= + 2îN. The force the electron would experience if it were moving with a velocity 
= 2
m/s at the same point is
= 2î m/s at a point in a magnetic field experiences a force = - 2î N. If the electron is moving with a velocity m/s at the same point, it experiences a force = + 2îN. The force the electron would experience if it were moving with a velocity = 2 m/s at the same point isOptions
A.zero
B.2
N
NC.- 2N
ND.Information is insufficient
Solution
⇒ - 2 ĵ = - e
⇒ B2 = 0⇒ 2 î = - e
⇒B1 = 0then
= - e
