a. A wire with a constant linear charge density of 4.0 C/m is located at the origin and oriented along
the y-axis. A -3.0 C charge is placed along the x-axis at position x = 0.50m. Find the electric force
on the -3.0 C charge.
b. Another wire is placed at position x = 0.70m and oriented along the y-axis. A switch is turned on
and a current of 3.0 A flows in the direction of the +y-axis. If the -3.0 C charge is initially moving
with a speed of 6.0 m/s in the direction of 30° counterclockwise from the +x-axis in the xy-plane,
what is the magnetic force on the charge?
c. What is the sum of the electric and magnetic forces on the -3.0 C charge? Illustrate the problem and
your answers and draw the directions of the electromagnetic fields and forces.

- | Scientists in a laboratory onboard a zero-gravity spaceship setup and measure electric and magnetic fields in an experiment chamber. The scientists measure the magnetic field to point in the positive x-direction given by B = B,î. The scientists then measure the net force acting on a charged particle q moving through this chamber. The net force is measured to be F = -F,î + F2j. The particle is moving along the positive z-axis with a velocity given by i = v,k. What are the x and y components of the electric field as measured by the scientists? Express your answers in terms of q, vo, Ba, F1, and F2, as needed.arrow_forwardConsider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.arrow_forward1. A wire carrying a 40-A current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.42-N force on the 4.3 cm of wire in the field. What is the average magnetic field strength? Things to Prepare: 1. Draw a sketch of the scenario in your notebook. Draw a vector respresenting the average magnetic field generated by the strong magnet. As no other information is given, the vector can be drawn in any diretion. Draw the current-carrying wire with respect to the field vector drawn above, making sure that it is perpendicular to the field. B= Tarrow_forward
