hey dude thanks for all the help, but please correct the electric fields question number 15's b(i) as you wrote mistakenly that its 0.428 but its actually 0.0428

toda la razon bro

hi, i really need help, wouldnt a graph of electric field strength agaisnt distance of 2 positive spheres look the same as the graph of 2 oppositely charged spheres? if not then why? im so confused.

Officialnth

in 15 b) i) the answer is 0.0428 not 0.428

Indro Casalini

Yeah my bad I meant to say mathematically similar. Thank you for that!

For these definitions just look at the equations and outline the proportionalities in play.

Intuitive

They’re not related to each other, one deals with the relationship between charge and the other mass. But they do take similar forms mathematically. For Coulomb’s law (F = kQ1Q2/r^2) where k is a constant so F ∝ Q1Q2 & F ∝ 1/r^2 “The magnitude of force between two point charges is directly proportional to the product of the magnitude of the charges and inversely proportional to the distance of the square between them” (This is the most formal way to put it)

Intuitive

So since Coulomb's Law is in a sense related to Newton's Law of Gravitation, if a question says state Coulomb's Law would the answer be "the force of attraction between 2 charged particles is directly proportional to the product of their charges and inversely proportional to their separation squared"?
