Question

You used a function of current and some other constants to find B. B, according to this function, was constant. Considering the equation e/m = 8B^-2 * Vd^-2, and considering your data, is B constant for a given current? And how do you know this? B must be constant for a given current because the equation is made only from constants; B= (4/5)^1.5 mu_o N* I* r^-1 B must be constant because I want it to be constant since the lab manual told me it was constant. B was not constant, even though it said it was, because diameter of beam Is ginning bigger so B must change since the bigger d numerically makes the ratio V/d^2 get smaller. B, according to my data, was not a constant value. My Vd^-2 consistently decreased as the diameter increased, e/m can remain constant with a decreasing Vd^-2 only if B decreases as well.

Explanation / Answer

Then

e/m = 8B-2 * Vd-2

In given function

in order to find B we used i mean in the question they have used some constants

the correct answer would be

it is not a constant value

it coinsistently increased diameter and vice versa happens'

so it is not at al a constant

when u undergo proof of this you can clearly know it is not a connstant

D is correct ooption.
