- A small particle with negative charge q = -12 x 10-3 is traveling between two large parallel plates that have charges of equal magnitude and opposite sign. The speed of the particle is 550 m/s. There is a uniform magnetic field in between the plates with magnitude of 5.0 T and its direction is out of the page. What are the magnitude and direction of the uniform electric field between the plates if the particle travels in between the plates without being deflected?true or false? parts d and e only| 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.
