Answer:
The closer two charged objects are the stronger the electrical force between them.
Like charges repel and opposite charges attract.
The further away two charged objects are the weaker the electrical force between them.
Explanation:
Coulomb's law tells us about the electric force/electrostatic force/Coulomb force between two charged particles. The force (F) between the particles Q and q, separated by a distance r is given as,
where k = Coulomb constant.
It is evident from the equation that closer the charged particle force will be more. As the distance between the charge increases the force will be weaker. Also the like charges will repel and opposite charges will attract.

Is this a joke? Because if ur on brainly for english users you should change that
Explanation:
<span>2π/T = 2π/10 = π/5
y(x) = A sin (wx) = 0.75 sin (πx/5)
y(4) = 0.75 sin (4π/5) = 0.4408389392... ≈ 0.441</span><span>

Answer:
increasing the separation between the plates
Explanation:
The increase in the vacuum/separation between the plates in a parallel plate capacitor connected to a constant potential difference decreases the energy stored in the capacitor. the increase in the separation of the plates of a parallel plate capacitor reduces the capacitance of the capacitor because
Q(charge) = CV V = VOLTAGE , c = capacitance
E = 1/2 eAV^2/ D ( ENERGY STORED )
where D = distance between plates, e = dielectric, A = area of capacitor , V = potential difference
