How do forces between between electrical charges differ from forces between masses?
Gravitational forces are always attractive. Electrical charges are repulsive for same-type charges, and attractive for opposite-types.
Are the charges of protons always the same?
yes. protons always have positive charge.
What are the attractive forces of plasma?
The attractive forces are electrical forces between opposing charges.
What type of particles gather near the bottom of clouds before energy is released as lightning?
the answer is both positive and negitive charges and that is because to make lighting it has to be positive and negitive charges because if there is both 2 negitive charges will both repel and the same thing will happen to positive charges but when positive and negitive charges and positive charges will attract
What causes a substance to have a positive charge?
the object has to have more positive charges than negative charges.
How do charges flow?
Charges always flow from positive to negative.
Which charge has strong force of attraction?
Neither charge on its own has an attractive force. Opposite charges (positive-negative) will attract while like charges (negative-negative or positive-positive) will repel.
How do forces between between electrical charges differ from forces between masses?
Gravitational forces are always attractive. Electrical charges are repulsive for same-type charges, and attractive for opposite-types.
Which universal force can repel as well as attract?
The gravitational force is proportional to the product of the two masses involved. The product is always positive, since mass is always positive. The electrical force is proportional to the product of the two charges involved. The product can be positive or negative, since either charge can be positive or negative.
Are the charges of protons always the same?
yes. protons always have positive charge.
Is two positive charges attract each other?
Never. Like charges repel always.
What subatomic particle always has a positive charge?
Protons are the subatomic particles which have positive charges.
3 positive charges and 4 negative charges what is the overall charge of an atom?
If an atom has 3 positive charges (protons) and 4 negative charges (electrons), the 3 positive charges would "cancel out" 3 negative charges, with one negative charge left over. So the atom would have a charge of -1.
Is an electric charged attractive or repulsive?
Both. Opposite charges attract, like charges repulse.
What is the difference between coulombs law and gravitation law?
Their mathematical forms are identical. The differences are: -- The proportionality constants. Newton's is 'G'. Coulomb's is 1/4Πε0 . -- The variables in Coulomb's numerator are electrical charges and he doesn't care about masses. The variables in Newton's numerator are masses and he doesn't care about charges. (I'm not sure Newton even knew about charges.) -- Coulomb's charges have a choice of two signs, so his forces can be attractive or repulsive, just like the co-eds in my sophomore engineering classes. Newton's masses are always positive, the gravitational forces are always attractive, and to this day negative mass has never yet been observed .
Do positive objects contain only positive charges?
No. A positive ion merely has more positive charges (protons) than negative charges (electrons).
Why charge always directed from ive to-ive?
Charge is always directed from positive to negative because positive charges repel each other and attract negative charges. This convention was established by Benjamin Franklin, who assigned positive charge to the lack of electrons (which are negatively charged), creating a standardized direction for current flow.
