Ok that a good question

A particle has a charge of +1.5 µC and moves from point A to point B, a distance of 0.15 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPEA - EPEB = +9.0 10-4 J. (a) Find the magnitude and direction of the electric force that acts on the particle. _______N the direction of motion (along, against, perpendicular)
(b) Find the magnitude and direction of the electric field that the particle experiences. _______N/C the direction of motion (along, against, perpendicular)

Answers

The magnitude of the electric field is 4000 N/C while the direction of the electric field is along the direction of the motion of the charge.

Given to us

Charge of the particle, q = +1.5 µC = 1.5 x 10⁻⁶

Distance between points A and B, d = 0.15 m

The particle's electric potential energy at A and B

= $\rm EPE_A - EPE_B$ = +9.0x10⁻⁴ J

What is the magnitude and direction of the electric force that acts on the particle?

The electric charge in electric potential energy is equal to the work done by an electric field. therefore,

$\rm W=EPE_A - EPE_B$

W = 9.0x10⁻⁴ J

We know that work done by the system can be given as,

$\rm Work = force* displacement$

Substitute the values,

$9 * 10^(-4)= F * 0.15$

F = 1.5 x 10⁻³ N

Thus, the magnitude of the force is 1.5 x 10⁻³ N while its direction is along with the motion of the charge.

What is the magnitude and direction of the electric field that the particle experiences?

We know the relationship between electrostatic and electric force, therefore,

$\rm Force = charge* Electric\ field$

Substitute the values,

$6* 10^(-3)=1.5* 10^(-6) * \rm E$

E = 4000 N/C

Hence, the magnitude of the electric field is 4000 N/C while the direction of the electric field is along the direction of the motion of the charge.

Answer:

Part a)

$F = 6 * 10^(-3) N$

Direction of force is along the motion of charge

Part b)

$E = 4000 N/C$

direction of electric field is along the direction of motion

Explanation:

Part a)

As we know that the change in electric potential energy is equal to the work done by electric field

$W = EPE_A - EPE_B$

$W = 9.0 * 10^(-4) J$

now from the equation of work done we know that

$W = F.d$

$(9.0 * 10^(-4)) = F(0.15)$

$F = 6 * 10^(-3) N$

Direction of force is along the motion of charge

Part b)

As we know the relation between electrostatic force and electric field given as

$F = qE$

$(6 * 10^(-3)) = 1.5 * 10^(-6) E$

$E = 4000 N/C$

direction of electric field is along the direction of motion

( Pennfoster plz help ) Which of the following does not accurately describe the forces that exist with an atom? A. Electrons closer to the nucleus and electrons farther from the nucleus repel due to like charges. B. Electrons positioned farther away from the nucleus are less attracted to the nucleus than are electrons positioned closer to the nucleus. C. Electrons positioned closer to the nucleus have a greater attraction to the protons and are more likely to be discharged from the atom than electrons farther away. D. Electrons in an atom are attracted to the protons within the nucleus due to opposite charges.

Answers

I would say C i'm not 100% sure

Choice-C is nonsense.

Electrons positioned closer to the nucleus are closer to the protons in the nucleus and more strongly attracted to them. Therefore these electrons are LESS likely to be discharged from the atom than electrons farther away from the nucleus are.

What is the importance of the ozone layer?

Answers

Importanceofozonelayer:

The ozone shields the surface of the earth from ultraviolet UV radiation from the sun.
These radiations are highly damaging as they can cause cancer in both plants and animals, damage to eyes and immune system.
They can also lead to variations in global rainfall, ecological disturbances and dwingling of global food suppliers.

Explanation:

Formationofozonelayer:ozone at the higher level of the atmosphere is a product of UV radiations acting on oxygen O2 molecule. The higher energy UV radiations split apart some molecular oxygen( O2) into free oxygen (O) atoms.

Depletionodozonelayer:The amount of ozone in the atmosphere began to drop sharply in the 1980's . This decrease has been linked to synthetic chemicals like cholorofluorocarbons ( CFC's ) which are used as refrigerants and in fire extinguishers.
