    Potential Energy and the Electric Potential Difference

    I'm back again this week with a problem: A particle has a charge of +1.5 Micro Coulombs and moves from point A to point B, a distance of .20 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's...

    Electric Field Problem: Magnitude & Force Calculation for Cell Membrane

    Yet another problem I'm stuck on tonight... The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. Assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a...

    Calculating Electron Count and Net Charge in Water

    OK, I took that info and did my best to work out the problem... I came up with 3.34x10^26 which was very close to one of the answer choices provided by my professor. Anyone mind double checking me? The other 4 choices were: 4.25x10^25 1.62x10^26 1.08x10^25 5.05x10^26

    Calculating Electron Count and Net Charge in Water

    I think I can maybe go with that... It's been a while since I've done anything physics related so I'm extremely rusty. Thanks, I'll be back quick with a response.

    Calculating Electron Count and Net Charge in Water

    First post here, so I wanted to say hello first of all. Must admit this board seems quite helpful. Anyways, here's my problem I'm having issues with, any help would be great. Water has a mass per mole of 18.0 g/mol, and each water molecule (H2O) has 10 electrons. (a) How many electrons are...
