Air will break down (lose its insulating quality) and sparking will result if the field strength is increased to about 3 × 106 N

/C. What acceleration will an electron experience in such a field? The mass of the electron is 9.109 × 10−31 kg and the fundamental charge is 1.602 × 10−19 C.

Answer:

Explanation:

Given

Electric Field Strength E=3\times 10^6\ N/C

When a charged particle enters the Electric field it Experience a force in the direction of electric field (for positive charge and vice-versa for negative charge)

charge on Electron q=1.6\times 10^{-19}\ C

mass of electron m=9.1\times 10^{-31}\ kg

Force F=q\times E

F=1.6\times 10^{-19}\times 3\times 10^6

F=4.8\times 10^{-13}\ N

acceleration of electron a=\frac{F}{m}

a=\frac{4.8\times 10^{-13}}{9.1\times 10^{-31}}

a=0.527\times 10^{18}\ m/s^2

Suppose the charges attracting each other in the above situation have an equal magnitude. Find the charge.
LiRa [457]

The force between the two point charge when they are separated by 18 cm is 3 N

<h3>How do I determine the force when they are 18 cm apart?</h3>

Coulomb's law states as follow:

F = Kq₁q₂ / r²

Cross multiply

Fr² = Kq₁q₂

Kq₁q₂ => constant

F₁r₁² = F₂r₂²

Where

  • F₁ and F₂ are the initial and new force
  • r₁ and r₂ are the initial and new distance apart

With the above formula, we can obtain the force between the two point charge when they are 18 cm apart. Details below:

  • Initial distance apart (r₁) = 6 cm
  • Initial force of attraction (F₁) = 27 N
  • New distance apart (r₂) = 18 cm
  • New force of attraction (F₂) =?

F₁r₁² = F₂r₂²

27 × 6² = F₂ × 18²

972 = F₂ × 324

Divide both side by 324

F₂ = 927 / 324

F₂ = 3 N

Thus, the force when they are 18 cm apart is 3 N

John pushes his bed to the left overcoming the force of friction. On the free-body diagram below, which force represents the fri
mamaluj [8]

Answer:

<em>Force B</em>

Explanation:

<u>Friction Force </u>

It's a force that appears when an object is tried to move on a rough surface. There are two cases: when the object is at rest, we have the friction static coefficient and when the object is already moving, we have the dynamic coefficient. The static coefficient is usually greater than the second because it's harder to overcome the friction when the object is at rest.

We are told that John pushes the bed to the left with enough force to overcome the force of friction. If the movement is intended to be to the left side, the friction force appears to the right, since it always opposes to the movement. Thus the force B is the one who represents the friction force in this situation
