Q. A free point charge q and mass m is at rest as shown in the figure. A constant electric field E=E_oi + 2E_oj and a constant magnetic field B=B_ok 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 (E_o/B_o). d) none of these.
