1. The problem statement, all variables and given/known data A charged particle is moving in a circular path under the influence of a uniform magnetic field. Describe how the path will change if an electric field is added, in the same direction as the magnetic field. 2. Relevant equations 3. The attempt at a solution Well, I found that if intensity of the field is increased, the radius of the circle is decreased. and also that if they are both turned off, the particle will fly off to its tangent so I'm thinking that this will make the radius bigger..? I'm not really sure the diff between the magnetic field and electric field. Thanks.
