Answer:The answer is A
Explanation:
To determine the force, we use the equation
Fg= G m1 m2/r2
, where Fg is the force of gravity, G is the gravitational constant,
m1
is the mass of the first body,
m2
is the mass of the second body, and r is the radius. Hence, we have
Fg=6.67×10−11 N×m2/kg2×2.5 kg×2.5 kg/(0.50 m)2=1.7×10−9N
. Since this is a gravitational problem, the force on one body has the same force as the other body, but the directions are opposite.
Charge is actually either excessive number or electrons or shortage of them.
as you can't destroy the electron or create it - you can't destroy or create charge

When atoms, the basic units of chemical elements, combine into chemical compounds, they form molecules. Organisms have many different kinds of molecules, from water and simple salts to complex molecules such as carbohydrates, fats, proteins, and deoxyribonucleic acid (DNA). One protein, called hemoglobin, carries oxygen in the blood and is what makes blood red. Hemoglobin contains atoms of six different elements—carbon, hydrogen, oxygen, nitrogen, sulfur, and iron.
