yes, when i take the sq root, i get 7.328 E6 m/s...still not the answer!

Homework Statement An electron is released from rest at the negative plate of a parallel plate capacitor. The charge per unit area on each plate is σ = 1.70E-7 C/m2, and the plates are separated by a distance of 1.59E-2 m. How fast is the electron moving just before it reaches the positive...

yes, south means down the page... C) true, parallel currents attract each other...? E)false, because the wires produce a mag. out of page...?

Homework Statement In the picture below, the two wires carry current i1 and i2, respectively, with positive current to the right. The charge q is positive and has velocity v to the right. If i2 = 0 and i1 is greater than zero, then the force on q points into the page. If i1 = 0 and i2...

yeah, that's right! i must have messed up on the calculations somewhere!

Homework Statement A long solenoid has 100 turns/cm and carries current i. An electron moves within the solenoid in a circle of radius 2.20 cm perpendicular to the solenoid axis. The speed of the electron is 0.048 c (c = speed of light). Find the current i in the solenoid. Homework...

here is the pic...oops

1. Homework Statement [/b] Suppose in the figure that the four identical currents i = 13 A, into or out of the page as shown, form a square of side 64 cm. What is the force per unit length (magnitude and direction) on the wire in the bottom left hand corner? (N/m) Take the positive y direction...

Homework Statement An electron with kinetic energy 1.92 keV circles in a plane perpendicular to a uniform magnetic field. The orbit radius is 26.0 cm. Find the speed of the electron. Find the magnetic field. Find the frequency of circling. (Hz) Find the period of the motion...
