Question

Question 5B An electron is in a uniform magnetic field B that is directed out of the plane of the page, a, (Draw it). b. When the electron is moving in the plane of the page in the downward direction, the force on the electron is directed Choose one (i) toward the right (ii) out of the page iii) into the page (iv) toward the top of the page

Answer 1

of the Uniform magnetic field B coming out of the plane The electron is denoted as e. page. b When the electron is moving in the plane of the page in the downward direction i.e. -2 direction (say with velocity v) the force on the electron

is given by F = q (W x B) where q is the change of electron -lel { (-vê) x Bi} lelvBj :. The fonce acts along +ve y direction i.e. towand sight. the : Option (2) is correct.
