    Calculating potential from a nonuniform linear charge distribution.

    Okay, yes disregard my question. I was using a computer algebra system (Microsoft Mathematics) to solve the integral. I tried it on my TI-84 Plus and I got .01863 Volts. (This is what I get for being lazy).

    Car changing speed around a corner - find tangential and radial accel

    How about finding the angle between your acceleration vector given and the direction of the expected centripetal acceleration vector. Same, what is the angle between the expected tangential acceleration vector and the acceleration vector given?

    How Do You Calculate Electric Flux Through a Cube with a Central Charge?

    Further point, consider the relation between the flux and the enclosed charge. We know the equation \Phi \epsilon_{0} = q_{enc} holds for any Gaussian surface. So we know that \Phi must be the same for any Gaussian surface enclosing the charge in question. In this case a spherical...

    Calculating potential from a nonuniform linear charge distribution.

    Homework Statement The thin plastic rod has length L, and a nonuniform linear charge density λ = cx. With V = 0 at infinity, find the electric potential (in V) at point P1 on the axis, at distance d from one end. c = 28.9 pC/m^2 L = 12.0cm d = 3.00 cm Now, from what I can tell the left...

    A force acts on a particle based on position, determine work. Sign question.

    I have a question about this problem in relation to the way the solution manual handles it. Homework Statement A force Fx acts on a particle of mass 1.5kg. The force is related to the position x of the particle by the formula Fx = Cx3, where C = .50. IF x is in maters and Fx is in...
