Crossed electric and magnetic fields are established over a certain region. The magnetic field is 0.6000 T vertically downward. The electric field is 2.000 x 106 V/m horizontally east. An electron, traveling horizontally northward, experiences zero resultant force from these fields and so continues in a straight line. What is the electron's speed? m/s

An electron moves through a region of crossed electric and magnetic fields. The electric field E = 2 000 V/m and is directed straight down. The magnetic field B = 0.80 T and is directed to the left. Specify the directions of electric and magnetic forces on the electron if it moves into the paper. For what velocity v of the electron will the electric force exactly cancel the magnetic force?

An unknown charged particle passes without deflection through crossed electric and magnetic fields of strengths 187,500 V/m and 0.1250 T, respectively. The particle passes out of the electric field, but the magnetic field continues, and the particle makes a semicircle of diameter 25.05 cm. What is the particle's charge-to-mass ratio? Can you identify the particle? can't identify proton electron neutron

An electron travels through a region with non-zero electric and magnetic fields. The electric field is directed into the page (-k cap), the electron is moving to the right (+ i cap), and the net force on the electron is zero. a) Which component of the magnetic field must be zero? b) Which component of the magnetic field must be non-zero?

Suppose that a region with a uniform magnetic field B also has a uniform electric field E perpendicular to the magnetic field, an arrangement called crossed fields. Show that for a charged particle moving in such crossed fields in a direction perpendicular to both E and B, the electric force cancels the magnetic force, provided the particle has a speed v= E/B If the magnetic field is in the vertical upward direction and the electric field is in the northward...

An unknown particle moves in a straight line through crossed electric and magnetic fields with E = 1.5 kV/m and B = 0.034 T. If the electric field is turned off, the particle moves in a circular path of radius r = 2.7 cm.

• An electron, at rest, is accelerated through region 1, which has a 5000 V potential difference. It then enters region 2 where there is only a uniform magnetic field and it undergoes uniform circular motion (in a plane) of radius 0.954 mm. After subtending half a circle, the electron exits region 2, traveling in the opposite direction it was before entering region 2. (a) Draw a physical representation of this situation, complete with the direction of the electric and...

Crossed E and B Fields. A particle with initial velocity V = (5.85 * 10^3 m/s) j enters a region of uniform electric and magnetic fields. The magnetic field in the region is B= -(1.350 T) k . Calculate the magnitude and direction of the electric field in the region if the particle is to pass through undeflected, for a particle of charge (a) +0.640 nC and (b) -0.320 nC. You can ignore the weight of the particle.
