Question

This question relates to particles placed in the electric field shown below.
A particle is placed into the electric field $\left(E\right)$, which has a magnetic field superimposed on it as shown. Where in the electric field will the three particles named below be located after a short period of time if they start at Point $E$? The particle is an electron.

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

The correct option is A A

Electron is a negatively charged particle , so it will be repelled by negative plate and be attracted by positive plate , so it goes towards plate $A$. Now according to fig. point $E$ is outside the magnetic field so electron will not be affected by magnetic field because it is going from $E$ to $A$.
