How important is it to you to understand the math your applying? I am decent at math when it comes to remembering rules and applying everything systematically, and i do well at solving problems using the tools i am given, but sometimes i have trouble understanding exactly why certain rules work...
so what exactly do field lines represent? i still think the tangent of a field line is the direction of the net force.. the vector sum of the forces exerted by 2 charges on a particle in that field. are the lines of equipotential then perpendicular to the field lines?
and about magnetic...
I have a few questions about electromagnetism that no matter how many texts i read i can't seem to figure out, so i'll cut to the chase.
1) why is current in the opposite direction of the flow of electrons? Shouldn't it be in the same direction as the electrons are travelling?
2) How does...
Another question..
if one positively charged sphere Q, of mass m is held by a string attached to a vertical pole, and one negatively charged sphere is held at a distance, r, away from the sphere, how do i find the angle between the string and the vertical pole? i know to use coloumbs law to...
If a charged object experiences say, an attractive force, as it moves closer to the other charged object doesn't the force increase.. so how can you ever have uniform acceleration with moving charged objects? can't it only be instantaneous acceleration? how can you apply the kinematics equations...
