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...

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).

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...

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.

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...

Thank you tutors for your help that worked!

Homework Statement A) Calculate the work performed by an external agent to move a charge of -0.59x10-12 C from `i' to `b'. B) Calculate the magnitude of the electric field at `k' Homework Equations W = q∆V Where ∆V is the potential difference between the two potential lines...

yes that's the way I ended up doing it -13.35e-6+-8.65e-6

More sig figs worked thank you everyone!

Right but that doesn't change the answer numerically am I forgetting a step?

The E-field on sigma1 is going -x and so is sigma2 right?

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...

Its right! Thank you for responding so fast!

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...
