the Lorentz force law, and using Newton’s first law, determine the direction of the
electric field.? A stream of electrons, each with speed v = 5.9 × 10^6 m s-1 and travelling horizontally along the x-axis in the positive x-direction enters a region pervaded by a uniform magnetic field B. The electrons then describe a circle with radius R in the horizontal xy-plane, circulating anticlockwise as viewed from above.
Two large, parallel, metal plates 0.20 m apart and placed symmetrically on either side of the incoming electron beam, are now used to apply a uniform electric field in the region where the electrons were circulating. This electric field is such that the electron beam is no longer deflected but continues straight on in the original positive x-direction.
1)Starting from the Lorentz force law, and using Newton’s first law, determine the direction of the electric field.
2)What potential difference must have been applied to the plates?
can any one go through it step by step with me im having trouble please ?
