Questions
Statement 1: If an electron, while coming vertically from outer space, enter the earth's magnetic field, it is deflected towards west.
Statement 2: Electron has negative charge.
detailed solution
Correct option is A
We know that the direction of the earth's magnetic field is toward north and the velocity of electron is vertically downward. Applying Fleming's left hand rule, the direction of force is towards west. Therefore, an electron corning from outer space will be deflected toward west.Talk to our academic expert!
