A particle with a charge 7C and a mass of 20kg is traveling in a circular path around a fixed particle of charde -5C. The velocity is observed to be 3000m/sec.
A 9C particle with the same velocity is instead in the presence of a uniform electric field of 250N/C as shown. What is the magnitude and direction of the magnetic field so that it travels in a straight line?
