Thank you so much, that cleared things up :)

Wait, I'm confused.. isn't 1.6 x 10^-19 the charge of an electron?! Oh wait, is it because charge of electron = charge of proton if its neutral?

Homework Statement Two protons are 2.5fm apart. What is the magnitude of the electric force on one proton due to the other proton? Homework Equations Fe = K|q1||q2| / r2 The Attempt at a Solution Fe = (9 x 109)x(1.6 x 10-19)2 / (2.5 x 10-15)2 Fe = 37 N I got the answer but I don't...

update: okay i think for part B, Δr= 2λ ? could someone confirm if this is correct or incorrect?? thanks!

Oh okay... So.. There's No effect? :/

Yep! Was just wondering, while waiting for your reply I was looking up some stuff; would doubling the magnetic strength also double the EMF? -just a thought haha..

Thank you :) Umm well EMF is proportional to the rate of change of the magnetic flux? :S

Homework Statement A bar magnet is held stationary (with respect to the loop of wire) at the centre of the loop with the North pole sticking out one end and the South pole sticking out the other. What happens to the size of any EMF induced in the loop once the magnet has been replaced by a...
