Hello for my previous question with this image that was rejected because its a graded question, this is NOT a graded assignment. This is the AP test from 2019 that I am using to study for my AP test from the college board. There are answers posted already from the college board and all of this information can be found with a quick google search of this question. Thank you and it was rejected previously before that because I submitted help for subpart D-F. But it got rejected because I was told it was a writing question. Question D is asking to indicate below which quantities should be graphed to yield a straight line whose slope could be used to calculate a numerical value for the mass-to-charge ratio of an electron. So it's not writing while questions E & F are graph questions. If graph questions are not allowed then I will submit it to writing but I think there may have been a mistake? If not then can you help me complete just subpart D? AVВmass = mcharge = e-3. Two plates are set up with a potential difference V between them.

Question

Hello for my previous question with this image that was rejected because its a graded question, this is NOT a graded assignment. This is the AP test from 2019 that I am using to study for my AP test from the college board. There are answers posted already from the college board and all of this information can be found with a quick google search of this question. Thank you and it was rejected previously before that because I submitted help for subpart D-F. But it got rejected because I was told it was a writing question.

Question D is asking to indicate below which quantities should be graphed to yield a straight line whose slope could be used to calculate a numerical value for the mass-to-charge ratio of an electron. So it's not writing while questions E & F are graph questions. If graph questions are not allowed then I will submit it to writing but I think there may have been a mistake? If not then can you help me complete just subpart D?

3. Two plates are set up with a potential difference V between them. A small sphere of mass m and charge -e
is placed at the left-hand plate, which has a negative charge, and is allowed to accelerate across the space
between the plates and pass through a small opening. After passing through the small opening, the sphere
enters a region in which there is a uniform magnetic field of magnitude B directed into the page, as shown
above. Ignore gravitational effects. Express all algebraic answers in terms of V, m, e, B, and fundamental
constants, as appropriate.
(a)
i. What is the initial direction of the force on the sphere as it enters the magnetic field?
Into the page

ii. Describe the path taken by the sphere after it enters the magnetic field.
(b) Derive an expression for the speed of the sphere as it passes through the small opening.
(c) Derive an expression for the radius of the path taken by the sphere as it moves through the magnetic field.

An experiment is performed in which a beam of electrons is accelerated across the space between the plates and
passes through the small opening. After passing through the opening, the electrons travel in a semicircular path
and strike the right-hand plate. The potential difference between the plates is varied in regular increments, as
shown in the table below. For each potential difference, the magnetic field is varied in order to cause the beam to
strike the right-hand plate at a distance of 0.020 m from the opening.
