Electric force varies directly with the magnitude of each charge, and inversely with the distance between the charges.
but for short....
electrical force depends on the charge and distance
Answer:
The frequency of radiation is 
Explanation:
Given:
Wavelength
m
Speed of light

For finding the frequency of radiation,




Therefore, the frequency of radiation is 
2Na + Cl₂ → 2NaCl
Explanation:
The reaction of sodium metal with chlorine gas to produce sodium chloride is a typical example of synthesis reaction.
Combination or synthesis involves the formation of a single product from two or more reactants.
A + B ⇒ C
In this kind of chemical reaction, a single product is formed or some compounds by the union of elements is notable.
The driving force for this category of chemical reaction is the large and negative heat of formation of the product.
