Volts = 180
Diameter of Beam = 11
Radius of Beam = D/2 = 0.055 (cm)
1/R (m) = 18.18
Current in Coil (I) = 1.02

My calculations for B is not coming out correctly
nor is my calculation for e/m

How do I go about doing this. I mean I think Im inputting it incorrectly into my calculator.

I am constantly trying with the formula but my answers aren't correctly coming out

You need to more completely state the problem. I don't see what a beam has to do wth a coil.

I tried inputting it like this exactly for B :

8 x 4pix10^-7x130x 1.02
------------------------------------------------
.055 x Sq.rt 125

I get my answwer to be .2709

When I plug that in for e/m by finding the slope

V squared
------------------
slope squared

2(180)
------------
.0250^2 ( this was the average slope of 2 points on my data)

= .00576

this is for sure incorrect because i cant even calculate the experimental error like this

Our data table which was given to us is set up in that way.

From the Diameter of the beam we took the radius in cm's
