An ionized gas contains both +ve and -ve ions which are initially at rest. The gas is subjected to `vecE` toward positive x-axis, magnetic field along +ve z axis. Then.find the direction of deflection of
a) +ve charged ions b) -ve charged ions

Explanation

To solve the problem, we need to analyze the motion of both positive and negative ions in the presence of an electric field (E) and a magnetic field (B).

### Step-by-Step Solution:

1. **Identify the Fields and Their Directions**:
- The electric field \( \vec{E} \) is directed along the positive x-axis.
- The magnetic field \( \vec{B} \) is directed along the positive z-axis.
