Explanation:

Theory of electrical forces

Because the particle q₃ is close to two other electrically charged particles, it will experience two electrical forces and the solution of the problem is of a vector nature.

Equivalences:

1nC= 10⁻⁹C

1cm = 10⁻²m

Data

q₁=4.96 nC = +4.96*10⁻⁹C

q₂=-1.99 nC = -1.99*10⁻⁹C

d₂= 2.98 cm

Graphic attached

The directions of the individual forces exerted by q₁ and q₂ on q₃ are shown in the attached figure.

The force (F₁₃) of q₁ on q₃ is repulsive because the charges have equal signs.

 the force F₂₃ of q₂ and q₃ is attractive because the charges have opposite signs.

Calculation of the forces exerted on the charge q₁ and q₂ on q₃

To calculate the magnitudes of the forces exerted by the charges q₁, q₂, on q₃ we apply Coulomb's law:

F₁₃=k*q₁*q₃/d₁² =9*10⁹*4.96*10⁻⁹*5.99*10⁻⁹/(49.96*10⁻³)²=10.7**10⁻⁵ N

F₂₃=k*q₂*q₃/d₂² =9*10⁹*1.99*10⁻⁹*5.99*10⁻⁹/(2.98*10⁻²)²=12.08*10⁻⁵ N

F₁₃x=F₁₃cosβ=10.7*10⁻⁵* (4.01/4.996)=8,56*10⁻⁵ N  (+x)

F₁₃y=F₁₃sinβ= 10.7*10⁻⁵* (2.98/4.996)=6,38*10⁻⁵ N  (+x)

F₂₃x= 0

F₂₃y= F₂₃=12.08*10⁻⁵ N (-y)

A) x-component of the total force exerted on the third charge by the other two (Fn₃x)

Fn₃x= F₁₃x + F₂₃x= 8,56*10⁻⁵ N + 0

Fn₃x =8,56*10⁻⁵ N (+x)

B)  y-component of the total force exerted on the third charge by the other two (Fn₃y)

Fn₃y = F₁₃y + F₂₃y= 6,38*10⁻⁵ N - 12.08*10⁻⁵ N

Fn₃y = 5.7*10⁻⁵ N  (-y)

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

c) power lifting, will be your answer.
