Two parallel current carrying wires are separated by 12 cm and each are 50 cm in length. The currents travel in the same direction for each wire (coming out of the page). One wire (on the left) has a current of 4 A and the other wire's current is 6 A.
a) Determine the Force acting each wire due to the other one:
b) Determine the location directly between the wires such that the Net Vertical Magnetic Field is Zero: i.e. Bnet= B1 + B2 = 0
An anemometer for measuring wind speed consists of four metal cups, each of mass m = 140 g, mounted on the ends of four essentially massless rods of length R= 0.37 m. The rods are at right angles to each other and the structure rigidly rotates..
An extremely thin film of soapy water (n=1.36) sits on top of a flat glass plate with n=1.11. What is the thickness of the film
Four charges are placed in a three-dimensional space. The charges have magnitudes 2 nC, -4 nC, 1 nC, and -9 nC. If a Gaussian surface encloses all the charges, what will be the electric flux through that surface?
A charge q = -6.0 µC is moved 0.25 m horizontally to point P in a region where an electric field is 250 V/m directed vertically, as shown. What is the change in the electric potential energy of the charge?
