Two charges 10uC (point A) and -10uC (point B) are placed 10cm from each other. Find the electric field at a point P perpendicular bisector of AB at a distance 12cm from the middle. Can someone get me started on this one? I'd appreciate any help. Thanks

Two charges (+4C and -3C)are separated by .00002m. What is the electrostatic force and its direction? Using Coulomb's law, I arrived at 2.696 x 10^20 J. Would the direction be said to be "towards the positive charge"? Is this correct? Thanks

So what does this have to do with helping astronomers understand the development of the solar system? When the Earth rotates on its axis, is this part of angular momentum being conserved? Does angular momentum show the astronomers how the earth and other planets rotate?
