(c)
(d) The three lines belong to the ultraviolet region.
Answer:
K = 1.525 10⁻⁹ x⁴ + 4.1 10⁶ x
Explanation:
To find the variation of kinetic energy, let's use the work energy theorem
W = ΔK
∫ F .dx = K -K₀
If the body starts from rest K₀ = 0
∫ F dx cos θ = K
Since the force and displacement are in the same direction, the angle is zero, so the cosine is 1
we substitute and integrate
α ∫ x³ dx + β ∫ dx = K
α x⁴ / 4 + β x / 1 = K
we evaluate from the lower limit F = 0 to the upper limit F
α (x⁴ / 4 -0) + β (x -0) = K
K = αX⁴ / 4 + β x
K = 1.525 10⁻⁹ x⁴ + 4.1 10⁶ x
in order to finish the calculation we must know the displacement

Answer:
v = 302.923 m/s
Explanation:
We can answer this question using conservation of energy. Since there is no energy loss (e.g. no viscous drag) the energy when they are far apart and the energy when they barely touch must be the same.
The initial energy must be equal to the sum of their kinetic energies, since they are far apart to feel their electrical interaction.
Ei = (1/2)mv1^2 + (1/2)m*v2^2
Let us consider that they move with the same speed:
Ei = mv^2
If we consider the case when they barely touch, there won't be any kinetic energy, just pure electromagnetic energy:
Ef = k q1q2/(r1+r2) = k q1q2/(2r1)
Since Ei = Ef
v^2 = (k/m) q1q2/(2r1)
where
k = 8.98755 x10^9 Nm^2/C^2
m = 9.05 x10^-14 kg
q1 = −2.10 pC
q2 = −3.30 pC
r1 = 3.75×10^−6 m
v^2 = 91762.4 m^2/s^2
v = 302.923 m/s
