Force vector is given as
![F = 10\hat i + 20\hat j + 27.2\hat k](https://tex.z-dn.net/?f=F%20%3D%2010%5Chat%20i%20%2B%2020%5Chat%20j%20%2B%2027.2%5Chat%20k)
now we need to find the magnitude of this force
as we know that
![F_x = 10](https://tex.z-dn.net/?f=F_x%20%3D%2010%20)
![F_y = 20](https://tex.z-dn.net/?f=F_y%20%3D%2020%20)
![F_z = 27.2](https://tex.z-dn.net/?f=F_z%20%3D%2027.2%20)
so here we will find the net force
![F_{net} = \sqrt{F_x^2 + F_y^2 + F_z^2}](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20%5Csqrt%7BF_x%5E2%20%2B%20F_y%5E2%20%2B%20F_z%5E2%7D)
![F_{net} = \sqrt{10^2 + 20^2 + 27.2^2}](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20%5Csqrt%7B10%5E2%20%2B%2020%5E2%20%2B%2027.2%5E2%7D)
![F_{net} = 35.2 N](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%2035.2%20N)
so it is having magnitude as 35.2 N
The crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.
Ionic solids are crystalline in nature. This means that the ions that compose them are arranged in an orderly manner to form a crystal lattice.
This crystal lattice is composed of a regular repeating pattern called the unit cell. The ions in these unit cells are held together by strong electrostatic forces.
Hence, the crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.

Answer:
*If the particles are deflected in opposite directions, it implies that their charges must be opposite
*the force is perpendicular to the speed, therefore it describes a circular movement, one in the clockwise direction and the other in the counterclockwise direction.
Explanation:
When a charged particle enters a magnetic field, it is subjected to a force given by
F = q v x B
where bold letters indicate vectors
this expression can be written in the form of a module
F = qv B sin θ
and the direction of the force is given by the right-hand rule.
In our case the magnetic field is perpendicular to the speed, therefore the angle is 90º and the sin 90 = 1
If the particles are deflected in opposite directions, it implies that their charges must be opposite, one positive and the other negative.
Furthermore, the force is perpendicular to the speed, therefore it describes a circular movement, one in the clockwise direction and the other in the counterclockwise direction.
It is actually inference because inference is using observation and background to reach a logical conclusion
