Two charges of -4.0 μc and -5.0 μc are held fixed at the lower two corners of an equilateral triangle of side length 2.0 m, in a vacuum. how much energy to move a point charge of +3.0 μc from a point midway between the other two charges is requi apex of the triangle?

Joules

Explanation:

= length of each side of triangle = 2 m

= initial distance of charge from other two charges at the lower two corners = (0.5) L = (0.5) (2) = 1 m

= final distance of point charge from other two charges at the apex of triangle = 2 m

= point charge = 3 x 10⁻⁶ C

= one of the charge on lower two corners = - 4 x 10⁻⁶ C

= other charge on lower two corners = - 5 x 10⁻⁶ C

= Energy required to move the point charge

Energy required to move the point charge

Joules

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
