Q. A free point charge q and mass m is at rest as shown in the figure. A constant electric field E=Eoi + 2Eoj and a constant magnetic field B=Bok is present in the region. The speed of the particle when it reaches the point (3,2,1) , is : a)8q.Eo/m b)14q.Eo/m c) (14q.Eo/m)x (Eo/Bo). d) none of these.Please solve this question.Rates and Salute guaranteed..Nitish..
