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

An alph-particle is travelling at right angles to magnetic field with a speed of 6 x 10 m/s

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

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

F_m = qVB sin θ

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

m = 4 amu = 6.64 x 10^-27 kg

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

On simplifying we get

= 3.84 x 10^-14 N

Acceleration a = F_m/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.

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