Answer: Option (4) is the correct answer.
Explanation:
Relation between potential energy and charge is as follows.
U = ![\frac{1}{4 \pi \epsilon_{o}}[\frac{q_{1}q_{2}}{r_{12}} + \frac{q_{2}q_{3}}{r_{23}} + \frac{q_{3}q_{1}}{r_{31}}]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%20%5Cpi%20%5Cepsilon_%7Bo%7D%7D%5B%5Cfrac%7Bq_%7B1%7Dq_%7B2%7D%7D%7Br_%7B12%7D%7D%20%2B%20%5Cfrac%7Bq_%7B2%7Dq_%7B3%7D%7D%7Br_%7B23%7D%7D%20%2B%20%5Cfrac%7Bq_%7B3%7Dq_%7B1%7D%7D%7Br_%7B31%7D%7D%5D)
As it is given that 
, 
, and 
.
Distance between the charges = 1 cm = 
(as 1 cm = 0.01 m)
Hence, putting these given values into the above formula as follows.
U =
= ![9 \times 10^{9} [\frac{1 \times 10^{-8} \times 2 \times 10^{-8}}{10^{-2}} + \frac{2 \times 10^{-8} \times 3 \times 10^{-8}}{10^{-2}} + \frac{3 \times 10^{-8} \times 1 \times 10^{-8}}{10^{-2}}]](https://tex.z-dn.net/?f=9%20%5Ctimes%2010%5E%7B9%7D%20%5B%5Cfrac%7B1%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%202%20%5Ctimes%2010%5E%7B-8%7D%7D%7B10%5E%7B-2%7D%7D%20%2B%20%5Cfrac%7B2%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%203%20%5Ctimes%2010%5E%7B-8%7D%7D%7B10%5E%7B-2%7D%7D%20%2B%20%5Cfrac%7B3%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%201%20%5Ctimes%2010%5E%7B-8%7D%7D%7B10%5E%7B-2%7D%7D%5D)
= ![9 \times 10^{9} [2 + 6 + 1.5]](https://tex.z-dn.net/?f=9%20%5Ctimes%2010%5E%7B9%7D%20%5B2%20%2B%206%20%2B%201.5%5D)
= 
J
= 0.00085 J
Thus, we can conclude that the potential energy of this arrangement, relative to the potential energy for infinite separation, is about 0.00085 J.
Hello!
Sulfuric acid (H₂SO₄) is a strong diprotic acid. "Diprotic" means that the acid donates 2 protons when dissociating in water to form ions. This happens in a series of two steps which are described below. The first reaction is basically a complete reaction while the second one is an equilibrium:
H₂SO₄(aq) + H₂O(l) → HSO₄⁻(aq) + H₃O⁺(aq)
HSO₄⁻(aq) + H₂O(l) ⇄ SO₄⁻²(aq) + H₃O⁺(aq)
Have a nice day!
Answer:
B
Explanation:
The cell membrane cannot receive or recognize chemical signals
The answer is ( The concentrations of the products and reactants do not change.)
Your body's skeletal system serves as a support structure. It is responsible for giving the body its structure, allowing mobility, producing blood cells, protecting organs, and storing minerals. The musculoskeletal system is another name for the skeletal system.
