Repeat above Question 3, if the charge is negative and the angle made by the boundary with the velocity is `theta = pi/6.`

Explanation

To solve the problem where a negative charge moves in a magnetic field with an angle of \(\theta = \frac{\pi}{6}\), we will follow these steps:

### Step 1: Understand the Setup
We have a negative charge \(Q\) moving with velocity \(V\) in a magnetic field \(B\). The angle \(\theta\) made by the boundary with the velocity is \(\frac{\pi}{6}\). The magnetic field is directed into the plane.

### Step 2: Determine the Direction of the Magnetic Force
For a negative charge, the direction of the magnetic force is given by the right-hand rule. Since the charge is negative, the force will act in the opposite direction to what it would for a positive charge.
