    What is the E-field through the rod?

    Homework Statement What is the electric field within the rod? (See attached document for full question) Homework Equations emf = -d(phi)/dt= integral (E dot dl) The Attempt at a Solution The rod is moving within a uniform magnetic field. There is no change in flux through the...

    A Rectangle Parallel to a Magnetic Field

    Yes because Magnetic Force = qv cross B thus it acts perpendicular to the magnetic field (B) since it is a cross product. The magnitude of the force is qvbsin(theta).

    A Rectangle Parallel to a Magnetic Field

    Homework Statement file:///Users/LabGuest/Desktop/CH26.tiff Homework Equations FB= qv cross B The Attempt at a Solution If the the rectangle is parallel to the magnetic field and we know that FB is perpendicular to the B field itself than there should be a net Torque but no net...

    Finding the Resistance of a cone

    never mind i found that (0,a) and (h,b). The radius than equals pi((b-a/h)x +a)^2. Now i can easily set up the integral.

    Finding the Resistance of a cone

    Homework Statement A solid truncated cone is made of a material of resistivity 5.10 Ohm*m. The cone has a height h = 1.16 m, and radii a = 0.34 m and b = 0.84 m. Assuming that the direction of current is parallel to the axis of the cylinder, what is the total resistance for this cone? (Use...

    Finding the E-field between two infinite plane charged sheets

    Homework Statement Two infinite-plane non-conducting, thin sheets of uniform surface charge p1 = 13.35 uC/m2 and p2 = -8.65 uC/m2) are parallel to each other and d = 0.245 m apart. (As shown in the diagram below.) What is the electric field between the sheets? (Note: the field is positive if...

    Finding the E-field of a mass hanging from a string

    9. [1pt] As shown in the figure above, a ball of mass 0.480 g and positive charge q =32.7microC is suspended on a string of negligible mass in a uniform electric field. We observe that the ball hangs at an angle of theta=15.0o from the vertical. What is the magnitude of the electric field...
