A particle of charge q and velocity v passes undeflected through a space with non zero electric field E and magnetic field B The undeflecting conditions will hold if a signs of both q and E are reversed b signs of both q and B are reversed c both B and E are changed in magnitude but keeping the product of B and E fixed d both B and E are doubled in ma
