Yes.
"Positively charged objects and negatively charged objects experience an attractive force."
My source is linked below.
Because the charges are equal in magnitude, the attraction is simultaneous.
The reason why some charges repel while unlike charges attract comes down to polarity. According to Newton, with every action there is an equal and opposite reaction. The reason comes down the the amount of protons and electrons in each atom. Equal amounts produce a repelling action where as charges with unequal protons and elections will cause the atoms to attract.
They are equal in magnitude but opposite in charge.
Whatever be the magnitude of charge, two charges will always exert equal force on each other. As force depends on the product of magnitude of charges, it will increase if magnitude is doubled but will remain same for both the charges.
they will attract if they have equal and opposite charges, such as Na and Cl
Think about it in science. If you had any atom with only positive charges or just negative charges it is an unstable atom, therfore you can't make anything out of it. They attract like puzzle pieces. To stabalize an object you need an equal amount of positive and negative charges.
That's going to depend on the magnitude of the charges. You've said that they're equal, and that's appreciated although unnecessary. But we still need a number.
Two equal charges will repel one another. Two different charges (i.e., a positive and a negative charge) will attract one another.
They are equal in magnitude but opposite in charge.
The electric charges of the proton and electron are equal in magnitude (size, strength), and opposite in sign.
If the directions of two vectors with equal magnitudes differ by 120 degrees, then the magnitude of their sum is equal to the magnitude of either vector.
if you add the vectors magnitude and equal to resultant the angle between them is 0
