Question

Considered two pairs of charges :

Pair 1 Pair 2
➕ ➖ ➕ ➕
Unlike charges Like charges
attract repel

Assuming the masses of all the charges are the same , how does the universal force of gravitational attraction differ in each case (given by formula : G*m1*m2/r²) ? Because in theory , they should have the same force of attraction . But this analogy is biased by the fact that one pair of charges attract each other and the other pair repel . So they may not have the same force of attraction .

Which of the two theories are correct and why ?

Answer 1

Answer:

Here both gravitational attraction force and electrical force are all different.

Gravitational force is always attractive for both like and unlike charges. In gravitational force charge doesn't matter.

But in case of electrical force,it might be attractive and repulsive both.

Electrical force is attractive for unlike charges and it accsts as repulsive force for like charges.
