A strong magnetic field is applied on a stationary electron. Then, the electron
- A moves in the direction of the field
- B moves in an opposite direction of the field
- C remains stationary
- D starts spinning
Answer & Solution
Correct Answer
(C) remains stationary
Step-by-step Solution
Detailed explanation
Force on an electron in an uniform magnetic field is given as
\(F=q v B\)
Since, the particle is stationary, i.e., \(v=0\)
\(\Rightarrow F=0\)
So, the electron remains stationary.
\(F=q v B\)
Since, the particle is stationary, i.e., \(v=0\)
\(\Rightarrow F=0\)
So, the electron remains stationary.
