Question

кулька заряд якої -6,4 нКл дотикається до такої ж незарядженої кульки скільки електронів перейшло з однієї кульки на іншу​

Answer 1

Ответ:

Объяснение:

Дано:

q₁ = - 6,4 нКл = - 6,4·10⁻⁹ Кл

q₂ = 0

e = - 1,6·10⁻¹⁹ Кл  - заряд электрона

______________

N - ?

1)

Суммарный заряд до взаимодействия:

Q = q₁ + q₂ = - 6,4·10⁻⁹ + 0  = - 6,4·10⁻⁹  Кл

2)

После соприкосновения заряд на каждом шарике:

q₁' = q₂' = q = Q / 2 = (- 6,4·10⁻⁹) / 2 = - 3,2·10⁻⁹  Кл

3)

Число электронов:

N = q / e

N = (- 3,2·10⁻⁹ ) / (- 1,6·10⁻¹⁹) = 2·10¹⁰

Answer 3

Coulomb's Law and Charge Transfer

When a charged sphere comes into contact with an uncharged sphere, charge can be transferred between them. According to Coulomb's law, the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between their centers. The formula for Coulomb's law is given by:

F = k * |q1 * q2| / r^2

Where: - F is the force between the charges - k is Coulomb's constant - q1 and q2 are the magnitudes of the charges - r is the distance between the centers of the charges

In the given scenario, if a charged sphere with a charge of -6.4 nC comes into contact with an uncharged sphere, we can calculate the charge transfer using the principles of conservation of charge.

Calculation of Charge Transfer

When the charged sphere touches the uncharged sphere, charge transfer occurs until both spheres reach the same potential. The charge transfer can be calculated using the formula:

q1 + q2 = 0

Where: - q1 is the charge of the first sphere - q2 is the charge of the second sphere

Given that the charge of the first sphere is -6.4 nC, and the charge of the second sphere is initially 0, we can calculate the charge transfer by rearranging the equation:

q2 = -q1

Substituting the value of q1:

q2 = -(-6.4 nC) q2 = 6.4 nC

This means that 6.4 nanoCoulombs of charge will transfer from the first sphere to the second sphere when they come into contact.

Conclusion

When a charged sphere with a charge of -6.4 nC touches an uncharged sphere, 6.4 nanoCoulombs of charge will transfer from the charged sphere to the uncharged sphere. This transfer occurs until both spheres reach the same potential, in accordance with the principles of conservation of charge.
