If a particle of charge 1μC is projected into a magnetic field `vecB = (2hati + yhatj- zhatk)` T with a velocity `vecV = (4hati+2hatj - 6hatk)ms^(-1)`, then it passes undeviated. If it is now projected with a velocity `vecV = hati + hatj` , then find the force experienced by it?

Explanation

To solve the problem step by step, we will follow these instructions:

### Step 1: Understand the conditions for the particle to pass undeviated
The particle passes undeviated in the magnetic field when its velocity vector \( \vec{V} \) is either parallel or antiparallel to the magnetic field vector \( \vec{B} \).

### Step 2: Write down the given vectors
We have:
- Charge \( Q = 1 \, \mu C = 1 \times 10^{-6} \, C \)
