An `alpha`-particle of mass `6.65xx10^-27kg` is travelling at right angles to a magnetic field with a speed of `6xx10^5ms^-1`. The strength of the magnetic field is `0.2T`. Calculate the force on the `alpha`-particle and its acceleration.

Explanation

To solve the problem, we need to calculate the force acting on the alpha particle and then find its acceleration. Here’s the step-by-step solution:

### Step 1: Determine the charge of the alpha particle
An alpha particle consists of 2 protons and 2 neutrons. The charge of a proton is approximately \(1.6 \times 10^{-19}\) coulombs. Therefore, the charge \(Q\) of the alpha particle is:
\[ Q = 2 \times (1.6 \times 10^{-19}) = 3.2 \times 10^{-19} \text{ C} \]
