Question

4. An electron enters a magnetlc fleid at right angles to it, as shown in figure. The direction of
force acting on the electron will be
1
Magnetic field .
Electron
(a) To the right
(b) To the left
(c) Out of the page
(d) Into the page​

Answer 1

Answer:

The correct answer is (d). According to Fleming's Left Hand rule, the direction of force is perpendicular to the direction of magnetic field and current. Here, since the direction of current is taken opposite to the direction of motion of electrons, the force is directed into the page.

Hope it will help you Please mark me as brainliest.

Answer 2

Answer:

the correct answer is D accordingly to Fleming's left hand rule the direction of force is perpendicular to the direction of magnetic field and current and since the direction of current is take opposite to the direction of motion of electrons the force is directed into the page
