An electron emmited by a heated cathode and accelerated through a potential difference of `2*0kV` enters a region with a uniform magnetic field of `0*15T`. Determine the trajectory of the electron if the field (a) is transverse to its initial velocity (b) makes an angle of `30^@` with the initial velocity.

Explanation

To solve the problem step by step, let's break it down into two parts as per the question.

### Part (a): Magnetic Field Transverse to Initial Velocity

1. **Understanding the Situation**:
- An electron is emitted from a heated cathode and accelerated through a potential difference of 2 kV.
- It enters a magnetic field of 0.15 T that is perpendicular to its velocity.
