Answer:
The ratio (U₁/U₂) = 6
Explanation:
U, the potential energy is given as
U = kqQ/r
k = Coulomb's constant
q = charge we're concerned about
Q = charge of the negative plate of the capacitor
r = distance of q from the negative plate of the capacitor.
For charge q₁
U₁ = kq₁Q/s
U₂ = kq₂Q/2s
But q₂ = q₁/3
U₂ becomes U₂ = kq₁Q/6s
U₁ = kq₁Q/s
U₂ = kq₁Q/6s
(U₁/U₂) = 6
When Ag(silver) reacts with CuCl2, Ag displaces Cu from CuCl2 and forms AgCl which is soluble and brownish red solid precipitate is left in the solution.
Hence option D is correct.
Hope this helps!

Where is the rest of the article to read form at?
Explanation:
Research studies are made because they want to solve problems that are occurring in the society. The benefits of research would eventually benefit the politics, especially because they have the power to implement these solutions to the problems. They don't usually delve into research because it is too technical. It is not their area of expertise. Questions may come up that they can't answer.
