A particle with charge `+Q` is moving on `X - Y` plane.
Magnetic field existing in the region is given as `vecB = B_(o)hatk`.
At a certain instant of time net magnetic force acting on the particle is `vecF = F_(0) hati + 2F_(0)hatj`. Find the instantaneous velocity of particle.

Explanation

To find the instantaneous velocity of a charged particle moving in a magnetic field, we can use the Lorentz force equation, which relates the magnetic force acting on a charged particle to its velocity and the magnetic field. Let's break down the solution step by step.

### Step-by-Step Solution:

1. **Identify Given Quantities**:
- Charge of the particle: \( +Q \)
- Magnetic field: \( \vec{B} = B_0 \hat{k} \)
- Magnetic force: \( \vec{F} = F_0 \hat{i} + 2F_0 \hat{j} \)
