I've included a picture. Two charges Qc and -Qc(Qc = 4 µC) are fixed on the x-axis at x = -7 cm and x = 7 cm, respectively. A third charge Qb = 5 µC is fixed at the origin. A particle with charge q = 0.3 µC and mass m = 5 g is placed on the y-axis at y = 14 cm and released. There is no...

1}If the electric field is zero in some region, must the potential also be zero?An example? 2}Give an example of a conductor that is not an equipotential.Is this conductor in electrostatic equilibrium? 3)If a high voltage cable falls on top of your automobile, will you probably be safest...

Don't know where to go Get stuck at every corner. Here it is "A small droplet of oil of 50^10*-6m radius is sitting inside of an electric field 500^10*3 N/C which is pointing straight up. What must be the charge on the oil droplet so that the electrostatic force cancels out due to gravity? The...

there are two forces, the nuclear force which binds protons and neutrons together. However as the size of the nucleus gets larger the electrostatic force of repulsion in the nucleus overcomes the strong nuclear force. so larger atoms breakdown to form smaller atoms, why does the electrostatic...

Here is the question... A pith ball of mass 1.5g is suspended along a string which is attached to a non movable point, when a pith ball of equal charge and mass is brought close to the original pith ball. A state of equilibrium is reached and the pith balls are 2.6cm apart and the string...

"compression" of an electrostatic charged sphere Everytime i propose a new motion machine from my ignorance or misunderstunding of physics, your explanations solve some questions, but open new others: I proposed a system that acumulated electrons on a sphere surrounded by an electrons...

Hello everybody! Many changes since the last time i was here!. Now, I've got a question that i can't stop think about. I hope you could help me. We all know the excess of charges on connected conductors always tends to distribute equally... ALWAYS? Take a look to this animation...
