Threepointchargeshaveequalmagnitudesandarelocatedonthesameline. The separation d between A and B is the same as the separation b

etween B and C. One of the charges is positive and two are negative, as the drawing shows. Consider the net electrostatic force that each charge experiences due to the other two charges. Rank the net forces in descending order (greatest first) according to magnitude. (a) A, B, C (b) B, C, A (c) A, C, B (d) C, A, B (e) B, A, C

Answer:

the descending order of the forces is

          B A C

Therefore the correct result is e

Explanation:

To answer this exercise we must use that the forces are vector magnitudes and the value is given by Coulomb's law

                   F = k q₁q₂ / x²

Consider the following scheme                          

              A    B     C

             -q  + q   + q

                  x      x

The forces are

           F_AB = k q² / x²

           F_AC = k q² / 4x²

           Fo = k q² / x²

           F_AB = Fo

           F_AC = ¼ Fo

           F_BC= F_AB

The forces on the charge A are

          F_A = F_AB + F_AC

          F_A = ​​Fo + ¼ Fo

          F_A= 5/4 Fo

The forces on the charge B

        F_B = -F_AB - F_BC

        F_B = - Fo - Fo

        F_B = -2 Fo

The forces on the load C

        F_C = F_BC –F_AB

        F_C = Fo - ¼ Fo

        F_C = ¾ Fo

For this distribution of charges the descending order of the forces is

          B A C

Therefore the correct result is e

If the charge distribution has the scheme          

              A      B     C

             + q   -q    +​​q

                    x     x

Force on A

           F_A = FA_B - F_BC

           F_A = Fo - ¼ Fo = ¾ Fo

Force on B

         F_B = F_AB –F_BC

        F_B = 0

Force on  C

          F_C = F_AC - F_BC

          F_C = ¼ Fo - Fo

          F_C = - ¾ Fo

For this distribution of charges the descending order of the forces is

          A B C

result is  a

Answer: B, C, A

Explanation:

Electrostatic force F = kq²/d²

Let the force on A be Fa, and B be Fb and C be Fc.

For Fa, distance between A and B is d, and distance between A and C is 2d

For Fb, distance between B and A is d, and distance between B and C is d

For Fc, distance between C and B is d, and distance between C and A is 2d

Also, the charge of each charge affects the sign of the force.

Critical Thinking 1. One day, a group of neighbourhood degs Started barking on their own. The residents living in that area are
liberstina [14]

The reason behind the barking of the group of neighborhood dogs could be <u>Territorial/Protective</u> or  <u>Alarm/Fear</u>.

What is bark or barking?

Dogs are known for making the most prevalent barking noises. Wolves, coyotes, foxes, seals, and barking owls are a few other creatures that make this sounds. The most typical onomatopoeia for this sound in English, particularly for large dogs, is "woof." The word "bark" can also be used to describe the sound made by numerous canids. A bark is a brief vocalization, as per the researchers at the University of Massachusetts Amherst.

Territorial/Protective: When a person or another animal enters their perceived area, your dog may bark excessively, depending on the breed. The barking frequently gets louder as the threat draws closer. When your dog barks in this manner, he will appear vigilant and sometimes even hostile.

Alarm/Fear: Some dogs will bark in alarm or fear at any sound or item that draws their attention or alarmed them. It's not just in their home country where this can occur. When they are afraid, their tails will be tucked and their ears will be pulled back.

How do you know that light travels faster than
Dahasolnce [82]

Answer:

Explanation:

Answer

How about a thunder storm. I don't know if you live in a city or out in the sticks as I do. Lighting is very obvious and it is not a good idea to be out when experiencing a thunderstorm, especially in an open field. You might be the only thing around that will cause the lightning to be connected to the ground.#  Seconds later, you will hear the thunder which is quite harmless. If you live in the city, observing this is not quite so easy. There are all kinds of buildings around and some of them may block your view.

#The great golfer, Lee Travino, was "hit" by lightening storm twice while playing in tournaments.
