If you were to plot T^2 versus ms using the equation T^2= (4pie^2/k)(ms +mw) how would you calculate the value for mw?

can someone please help me? What do they mean by plot T^2 verus ms?

what are ms, mw, and k

so say plot T^2 vs ms means you plot T^2 on the Y (vertical) axis and ms on the X (horizontal) axis

Put

x = ms
y = T^2
m = 4 pi e^2/k
c = 4 pi e^2 mw/k

Then the given equation is

y = mx + c

This is the equation of a straight line with gradient m and y intercept c.

So, to find mw, you look at the value of c on your graph and then rearrange the expression for c to calculate mw.
