6. What is the electric potential energy of a +3.0 μC charge placed at corner A?

Darina [25.2K]

The question is incomplete. The complete question is stated below:

Two point charges are held at the corners of a rectangle as shown in the figure. The lengths of sides of the rectangle are 0.050 m and 0.150 m. Assume that the electric potential is defined to be zero at infinity.

a. Determine the electric potential at corner A.

b. What is the electric potential energy of a +3 µC charge placed at corner A?

Answer / Explanation:

a )V(A) = 1 / 4πe° ( - 5 5x10∧6C / 0.150m + 2x10∧6C / 0.050m )

The answer to the equation above is : = +6.0x10∧4 j/c

b) U(A) = qV(A)= (3.0x10∧6C) (6.0x10∧4 . j/c) =

The answer to the equation above is : =0.18 J

Explanation:

Where V(A) is equivalent to the electric potential

U(A) is equivalent to the electric potential energy

Does a reaction occur when aqueous solutions of silver(I) acetate and manganese(II) iodide are combined?

san4es73 [151]

Answer:

When aqueous solutions of silver(I) acetate and manganese(II) iodide are combined, an insoluble precipitate of silver(I) iodide is formed

Explanation:

It is an example of precipitation reaction.
When aqueous solutions of silver(I) acetate and manganese(II) iodide are combined, an insoluble precipitate of silver(I) iodide is formed.
Precipitation of silver(I) iodide is confirmed by it's yellow color.
Hence a reaction is observed.
Molecular reaction: $2Ag(OAc)(aq.)+MnI_{2}(aq.)\rightarrow 2AgI(s)+Mn(OAc)_{2}(aq.)$
