Electrical potential Definition and 110 Threads

I have no idea what principles i am supposed to use in this question? Could someone show me how to do this question please? Thanks :smile: Calculate the electrical potential energy of two protons separated by 1 nm, and compare it with their gravitational potential energy. Estimate how heavy...

1. Through what potential difference would an electron need to be accelerated for it to achieve a speed of 50.0% of the speed of light, starting from rest? The speed of light is c = 3.00 108 m/s. >> I'm really not too sure what to do with this problem. I took .50*3.00e8 and got 1.50e8...

[FONT=Comic Sans MS]I need help on these ?'s. They are very confusing to me. Can someone please help me. -Here they are: >Two charges are located along the x-axis. ONe has a charge of 6.4 micro C, and the second has a charge of -3.2 micro C. If the electrical potential energy associated...

point a is at a potentiall of +290...point b is at potential of -220...helium nucleus contains 2 neutrons and 2 protons...neutrons are electrically neutral...what kinetic energy does particle have after accelerating from rest at point a to b...in electron volts

My question is how is electrical potential actually transmitted through an electric circuit. A charge (i.e. and electron) is moved through an magnetic field (as in a generator), the particle gains electric potential due to the work performed on it in the generator. This potential is then used...

The potential is constant throughout a given region of space. Which of the following statements is true? Be sure you can justify your answer. The electric field may have places where it is zero, and places where it is nonzero in this region. The electric field is nonzero in this region...

Hello, I've been trying and trying to do this problem for quite a while now, and I can't seem to get an answer which agrees with the book. I figured that one metal sphere would then end up with a charge of 10^13 electrons (so I multiplied that by 1.60x10^-19 to get the charge of all the...

Suppose two protons are a small distance 2.5x10^-15m apart. What is the total electrical potential energy this system?

Electrical potential is constant everyplace on the surface of a charged conductor. Also, on the surface of an irregularly-shaped conductor, the charge density is high in convex regions with small radius of curvature (especially, for example, at sharp points), and low in regions of large...
