- At a particular instant an electron is traveling west to east with a kinetic energy of 10 keV. Earth's magnetic field has a horizontal component of 1.8105 T north and a vertical component of 5.0105 T down. (a) What is the path of the election? (b) What is the radius of curvature of the path?arrow_forwardUnreasonable results Frustrated by the small Hall voltage obtained in blood flow measurements, a medical physicist decides to increase the applied magnetic field strength to get a 0.500-V output for blood moving at 30.0 cm/s in a 1.50-cm-diameter vessel. (a) What magnetic field strength is needed? (b) What is unreasonable about this result? (C) Which premise is responsible?arrow_forwardAn electron in a TV CRT moves with a speed of 6.0107 m/s, in a direction perpendicular to Earth's field, which has a strength of 5.0105 T. (a) What strength electric field must be applied perpendicular to the Earth’s field to make the election moves in a straight line? (b) If this is done between plates separated by 1.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a collection,)arrow_forward

Point P in the center of the ring is 25 cm from the z-axis. An electron is ejected from P at a velocity of 1.0 × 106 m / s in the negative x direction.

They each carry an equal amount of current, I, in the directions that are shown. The lower two wires are 5.0 cm apart and being held stationary. What current I will allow the top wire to “float” such that it forms an equilateral triangle with the other two wires?arrow_forwardI 5 cm A rectangular loop (10 cm length and 5 cm width) placed 5 cm from a long straight wire in the x-y plane. both loop and wire carry 10 cm I the same current I = 3 A. the current directions are shown in the figure. a) Calculate the magnitude and direction of 5 cm the net force on the loop. b) What is the magnitude of the net torque on the loop and why?arrow_forward
