MgCO3 will remain undissolved and
NaNO3 will dissolve
The strength of electrical forces tells about the size of charge on the object.
<h3>What is infer about the strength of electrical forces?</h3>
The strength of the electric force between two charged objects depends on the amount of charge that each object have and on the distance between the two charges. When the amount of charge gets bigger, the force also gets bigger, and when the distance between the two charges gets larger, the force also gets smaller. Electric forces are the attraction present between two charge bodies.
So we can conclude that The strength of electrical forces tells about the size of charge on the object.
