    How Do You Calculate Electric Potential of a Nonuniformly Charged Rod?

    Oh! Okay, that makes sense (where X is treated like it's fixed but r(x) is still the distance from X to x, some point on the rod). Thank you!

    How Do You Calculate Electric Potential of a Nonuniformly Charged Rod?

    umm, I was until the change of variables part--unless I don't need a change of variables and integrated the wrong expression?

    How Do You Calculate Electric Potential of a Nonuniformly Charged Rod?

    [SOLVED] Electric potential Homework Statement The charge on the rod of the figure (length 2l, center at the origin) has a nonuniform linear charge distribution, λ = ax. Determine the potential V at: (a) points along the y-axis. (b) points along the x-axis. (Assume x > l) (express...

    Electric potential: point charge in a hollow charged conductor

    No, it doesn't add to the integral because E is 0 in that region. Okay, thank you for your help. :)

    Electric potential: point charge in a hollow charged conductor

    So are you saying that I should add all three potentials like this? ie, (3Q)/(16πε0r1) + [Q/(8πε0)](1/r - 1/r1) -I realize I derived the potential from r to r1 incorrectly. -Also, I didn't include the potential in the region from r2 to infinity when I first solved the problem because I...

    Electric potential: point charge in a hollow charged conductor

    [solved] electric potential: point charge in a hollow charged conductor Homework Statement A hollow spherical conductor, carrying a net charge +Q, has inner radius r1 and outer radius r2 = 2r1. At the center of the sphere is a point charge +Q/2. d) Determine the potential as a...

    Physics Thermodynamics - Finding Work

    Ah, thank you so much for the insight. (I'll have to try and work that out when I can find the time.)

    Physics Thermodynamics - Finding Work

    Homework Statement A 1.20 mol sample of an ideal diatomic gas at a pressure of 1.20 atm (P1) and temperature of 380 K (T1) undergoes a process in which its pressure increases linearly with temperature. The final temperature and pressure are 680 K (T2) and 1.83 atm (P2). (b) Determine the...
