A) Using Excel, or some other graphing software, plot the values of y as a function of x. (You will not submit this spreadsheet. However, the results will be needed later in this problem). x y
1 2.5
2 3.3
3 4.5
4 4.9
5 7.0
B) Use the trendline option to draw the best fit line for the above data and use it to determine the slope and y-intercept.

   y = 1.06 x + 0.14

            r² = 0.95

Explanation:

a) To make this graph, a spreadsheet-type calculation program is used, see attached.

On the y axis are the measured values

On the x-axis, the values checked in the experiment are placed.

From the graph we see that a linear graph and that one of the values has a strong deviation with respect to the others

b) The red line is the best straight line that can be drawn,

    for this the quality ajust is r²  

the closer to 1 the better the fit

the equation of the line is

            y = 1.06 x + 0.14

            r² = 0.95

glen is correct.

step-by-step explanation:

glen is correct because when you multiply 4 * 2 = 8.

and 4 * 3 = 12.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
