A strong magnetic field is applied on a stationary electron, thenA. moves in the direction of the field.B. remained stationary.C. moves perpendicular to the direction of the field.D. moves opposite to the direction of the field. |
Answer» Correct Answer - B As `vecF=vecq(vecv xx vecB)` As the electron is stationary, `therefore` velocity `vecv=0` `therefore" "vecF=0`. So, electron will remain stationary. |
