Electrical field Definition and 55 Threads

please help given insulator ball with radius R that charged with uniformed density p<0. the ball is charged with -3Q 3 colon charges with Q>0 each one, are found inside the ball (look at the draw) the charges found at triangle that it's sides are equal (each side length = d) and d<=2R...

Can someone let me know if I'm going in the right direction. The electrical force on a 2-columb charge is 60 Newtons, What iis the magnitude of the electric field? E =f/q E= 60/2 E=30 If a charge of +3 x 10 -6columbs sets up an electrical field, find: a. The magnitude of...

An electron is accelerated from rest for a time of 10R-9 seconds by a uniform electrical field that exerts a force of 8E-15 N on the electron. What is the magnitude of the electrical field? What equations should I use? There's E=F/q and E=kQ/r^2 They both don't work. The speed id the...

Please read this topic first. I have recently seen a proof (using Gauss' law) showing that there is no electrical field inside a charged metallic conductor (due to the carge on its surface). (i can provide this proof if needed) If that proof was right, then this must mean that the inner sphere...

Just going through some review questions and wanted to clear up some questions I had. I figure you guys like showing off how smart you are. First Question: Consider the parallel plate capacitor classroom demonstration. A. Write a mathematical expression for Gauss' Law. Describe the meaning...
