Question
An electron enters a magnetic field at a right angle to it as shown in the figure. The direction of force acting on the electron will be
- To the left
- To the right
- Out of the page
- Into the page
Hint:
Into the page
The correct answer is: Into the page
Using Fleming's left hand rule, direction of force is perpendicular to the direction of magnetic field and current. Thus direction of force is opposite to electron motion into the page at 90ﾟ
