Question 21 An electron moving in the direction of the +x-axis enters a magnetic field. If the electron experiences a magnetic deflection in the -y direction, the direction of the magnetic field in this region points in the direction of the -Z-axis +z-axis none of the choices given +y-axis -x-axis

16. (25) a.) Two electric charges, qq and q2 lie on the x-axis at positions of + 10 cm and - 10cm, respectively. What is the force on a third charge q3 that is placed at x = 0, if q1 = 10 µC, q2 = -10 µC and q3 = 20 µC? b.) An electron enters a uniform magnetic field whose magnitude is 1.5 T and direction is parallel to the + z-axis. If the electron's velocity is 2.0 î – 3.0 ĵ+1.0 k m/s what is the force on the electron? c.) The magnet in the diagram is moved to the left. Copy the diagram into your blue book and indicate the direction of the induced electric current, which you should find using Lenz's Law. What is the situation some time later, when the magnet has stopped moving? Explain your answers. Lume R

A proton moves perpendicular to a uniform magnetic field B at a speed of 2.10 x 10' m/s and experiences an acceleration of 1.90 x 1013 m/s in the positive x-direction when its velocity is in the positive z-direction. Determine the magnitude and direction of the field. magnitude direction ---Select--- v

The figure below indicates that I and I2 are in opposite direction. they have magnitude of 3A and 5A consecutively. they are also at radiuses 2m and 4m consecutively. What is the magnetic field magnitude? of I2 ENG 4) G 7/TV
