    Why multiply by cos(45°) when resolving electric field components

    Hello and thanks for the response. I did not understand that we had to deal with vectors in this problem. I have reviewed the text and I understand now. Finding the magnitude of the vectors of both x and y components is going to require multiplying by cos45 or cos(-45) which will give the...

    Why multiply by cos(45°) when resolving electric field components

    The first part of the above image is the question from the text, and below that is information from the solutions manual. I understand why we broke the components up into the x and y, I understand how we triangulated the distance between the center of our coordinate system and the charge to get...
