Two parallel long (Infinite for our purposes) wires are oriented along the z-axls. The figure below shows the (xy)-plane perpendicular to the wires, including the positions where the wires cross this plane. The wires carry some unknown electric currents 11 and 12, which you need to find from a single measurement of the magnetic field B=BXİ + By j at...

apart on the x-axis.
A -10.0 nC point and a +20. 0 nC point charge are 15.0 cm apart on the x-axis. What is the electric potential at the point on the x-axis where the electric field is zero? Express your answer with the appropriate units....
A wave with an amplitude of 2.5 cm, a frequency of 12 Hz and a wavelength of 45 cm travels down a string with a linear density of 0.00245 kg/m. What is the maximum speed and maximum acceleration of a point on the string as the wave passes?
Determine the direction of the force that will act on the charge in each of the following situations. A negative charge moving into the screen in a magnetic field that points downward. A negative charge moving downward in an electric field that points out of the screen. A positive charge moving to the left in a magnetic field that points...
1- For a uniform electric field, how is the electric potential energy similar to the gravitational potential energy in a uniform gravitational? 2-If a positive charge and a negative charge moving the same way in an electric field have the same change in electric potential energy? 3-For a positive charge moving in an electric field, which direction of motion will...
3. For a while in the early 20th century one proposed model for the structure of atoms was that a positive point charge (the nucleus) +Ze was at the center of a charged sphere of radius R and charge -Ze. To be clear, the negative charge in the sphere was proposed to be spread through the volume of the sphere,...

An electric-dipole antenna, broadcasting microwave electromagnetic radiation for mobile communications, is located on the roof of a 111-m-high building and is oriented vertically. Two observers measure the signal strength (radiation intensity) from this antenna. Observer A is on the roof of another building, at the same height as the antenna and at a distance of 1.61 km from it. Observer...
