A) Two ways to create a positive ion:

nirvana33 [79]

Positive ions are formed by atoms or molecules suffering an inelastic collision with an energetic electron in which an electron is lost from the atom or molecule (electron impact ionization). The degree of ionization of the plasma depends strongly on the electron density and energy distribution in the gas.

If charge on only one object is tripled, determine the new force between them:

Allisa [31]

Answer:

+3·F

Explanation:

The number of objects in the given system = 2 objects

The charge on each object are; q₁ = -Q, q₂ = -Q

The force acting between the objects = +F

The distance between the objects = 2·d

The formula for the force acting between two charged particles is given as follows;

$F=K \times \dfrac{q_{1} \times q_{2}}{r^{2}}$

Therefore, we get;

$F=K \times \dfrac{-Q \times -Q}{(2\cdot d)^{2}} = K \times \dfrac{Q^2}{4 \cdot d^2}$

By tripling the charge, q₁, on the first object, we get;

q₂ = 3 × (-Q)

$F_2=K \times \dfrac{-3 \cdot Q \times -Q}{(2\cdot d)^{2}} = K \times \dfrac{3 \cdot Q^2}{4 \cdot d^2} = 3 \times +F = +3\cdot F$

Therefore, the new force between them, F₂ = +3·F
