Problem 27.9: Velocity selector
Please wait for the animation to completely load.
The animation shows a 30-mg charged object entering a region where a magnetic field and/or electric field can be applied (position is given in centimeters and time is given in seconds). The magnitude of the charge is 4 x 10-3 C. Restart.
- Is the object positively or negatively charged? Explain.
- What is the magnitude of the electric field?
- What is the magnitude of the magnetic field?
- What voltage must be applied to the plates to create the electric field?
For an introduction to the velocity selector see Exploration 27.2.
