Question

An electron and a proton each travel with equal speeds around circular orbits in the same uniform magnetic field.The field is into the page. electron is less massive than the proton.electron is negatively charged and the proton is positively charged: a.)the electron travels clockwise around the smaller circle and the proton travels anticlockwise around the larger circle. b.)the electron travels anticlockwise around the smaller circle and the proton travels clockwise around the larger circle.

Answer 1

Answer:

Explanation:Dear Student,

                    Using flamings left hand rule you can find out that

Force on proton entering a region having magnetic field into the field of paper is such that it will move in a circle in anticlockwise direction and therefore electron in clockwise direction.

                  Radius of  circle in which a charge particle moves is directly proportional to mass and hence proton will move in a circle of larger radius.

                                                                            Hope it helps

Answer 2

Answer:

With the help of the left hand rule of Flemings you can get to the right answer.

The force on proton that enters a region with the magnetic field in the field of paper is so that it will move in the circle in anticlockwise direction.

Therefore, the electron will be in the clockwise direction.

The radius of the circle in which the charge particle moves is directly proportional to the mass.

Therefore, the proton will move in a circle of bigger radius.
