In the previous question,if the particle has`-Q` charge the time spend by the particle in the field will be .

Options

A. `T theta`
B. `2 T theta`
C. `T((pi+2theta)/(2pi))`
D. `T((pi-2 theta)/(2pi))`

Explanation

To solve the problem of finding the time spent by a particle with charge `-Q` in a magnetic field, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem Context**:
- We have a charged particle (now with charge `-Q`) moving in a magnetic field. The previous question established that a particle with charge `+Q` moves in a circular path within the magnetic field.

2. **Identify the Geometry**:
...
