At a large desk or on the floor, choose a position to represent the Sun, and place Mercury a few inches from it. Predict the relative distances between each of the other planets, and space them out accordingly. Do you think the

conclusion?

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

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.

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
