121.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 condition will hold if. (1)sign of both q and E are reversed (2)sign of both q and B are reversed (3) both B and E are changed in magnitude, but keeping the products of B and E fixed (4) both B and E are doubled in magnitude |
