5. a -6.5 μc charge experiences a downward electric force of 5.9 n. find the magnitude and direction of the electric field at the position of this charge.

Coulomb's law may be used to determine the overall force the tiny electric dipole applies to the positive charge q.

The force between two point charges is proportional to the product of the charges, according to Coulomb's law. The equation F = k * (q * p * cos) / d2 represents the overall force that the dipole applies to the charge q.

Where d is the distance between the charge q and the centre of the dipole, p is the dipole moment, is the angle between the direction of the dipole moment and the direction of the distance between the charge q and the centre of the dipole, and k is the Coulomb constant.

cosθ = x / d

As a result, the following is the final formula for the total force the dipole applied to the positive charge q:

F is equal to k*(q*p*x/d3).

When they are moved to a new separation of 8.0 cm, the electric force on each of them will be closest to 0.063 N.

Full question: When two point charges are 2.0 cm apart, each one experiences a 1.0-N electric force due to the other charge. If they are moved to a new separation of 8.0 cm, the electric force on each of them is closest to?

Given:

The point charges are initially at a distance of d = 2 cm.

The initial force experienced by them is F = 1 N.

The electrostatic force experienced by two charges q and Q is defined as,

                                     F = kqQ/d^2

Where

K is the constant and r is the distance between the charges.

The initial force experienced by them will be, F = 1N

Now, the final distance between the charges is changed to 8 cm which is equal to 4d.

So, the new force on the charges will be,

F = kqQ/(4d)^2 = 1/16 = 0.063N.

So, when they are moved to a new separation of 8.0 cm, the electric force on each of them will be closest to 0.063 N.

"Refraction" happens when light energy bends as it passes from one type of substance to another type. Therefore, option c is the correct answer.

Refraction is the bending of a light wave as it passes from one type of substance to another type. Refraction occurs as a result of changes in density and speed. For instance, light slows down as it enters water from air. When light travels through a fast medium and into a slow medium, the light beam is refracted, which causes it to bend in the direction of the boundary between the two media.

Refraction bending allows us to have lenses, magnifying glasses, peepholes in house doors, cameras, prisms, rainbows, movie projectors, and telescopes. Even our eyes rely on this light bending. We wouldn't be able to concentrate light onto our retina without refraction.

The mass of 10 trillion silver atoms is approximately 6.6 x 10^-7 grams.

To determine the mass of 10 trillion silver atoms, we need to know the atomic mass of silver. Silver is a chemical element with the atomic number 47 and its atomic mass is 107.87 amu (atomic mass units). One amu is equivalent to 1.66 x 10^-24 grams.

So, to find the mass of 10 trillion silver atoms, we need to multiply the atomic mass of one silver atom by the number of atoms:

mass = atomic mass * number of atoms

mass = 107.87 amu * 10^13 atoms

mass = 1.0787 x 10^-22 grams * 10^13 atoms

mass = 1.0787 x 10^-9 grams * 10^13 atoms

mass = 1.0787 x 10^4 grams * 10^13 atoms

A force sensor is a device used to measure force or weight. Force sensors are commonly used in a wide range of applications, including scientific experiments, industrial processes, and athletic training.

It is not possible to pull on a partner's force sensor without the force sensor pulling back. This is because of the basic principles of physics, specifically Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In other words, when a force is applied to an object, the object will respond with an equal and opposite force.

In the case of a force sensor, if you try to pull on the sensor, the sensor will respond by applying an equal and opposite force back to you. This is what makes the force sensor work; it measures the force applied to it and then provides a measurement of that force in response.

The second thing that Plato wanted to get rid of was poverty. He believed that poverty was a major source of social unrest and that it prevented people from living good lives. He argued that the state should take care of its citizens by providing them with the basic necessities of life, such as food, clothing, and shelter.
