The force on the a-particle is 3.84 x 10-14 N and the acceleration of the a-particle is 5.784 x 1012 m/s2

We are aware that a moving charge particle experiences magnetic force in a homogeneous magnetic field when

Fm = q (V x B) = qVB sin 0n

Fm = qVB sin θ

For α particle q = + 2e = 2 x 1.6 x 10-19 Coulomb

m = 4 amu = 6.64 x 10-27 kg

Fm = 2 x 1.6 x 10-19 x 6 x 105 x 0.2 x sin 900

On simplifying we get

= 3.84 x 10-14 N

Acceleration a = Fm/m = 3.84 x 10-14 N/ 6.64 x 10-27 kg

= 5.784 x 1012 m/s2

Effects of Force

Motion is described as a change in location with regard to time in physics. Motion, to put it simply, is the movement of a body. Motion is typically characterised as:

• Change in speed
• Change in direction

Here are some of the consequences that the Force can have.

1. A body at rest can be forced to move.
2. It can either slow down or stop a moving body.
3. It can quicken the pace of a moving object.
4. Along with altering its size and shape, it can alter the direction of a moving body as well.
