Sorry about that! Was basing it off memory lol. okay so i found the force between the charge of positive 2 and the proton to be 2.1e-8 N, and i found the other force to be 3.5e-8 N. then i found the x and y components of the forces, and that was 3.4e-8 and 7e-9, respectively. i then added this...

Homework Statement Diagram shows the separations of a proton, electron, and α particle (charge +2e). What is the force (magnitude and direction) on the proton? Homework Equations Addition of vectors, Coulomb's law The Attempt at a Solution I keep getting 82 degrees but the answer...

Yeah, I just got it, thanks !

Attached is the diagram for the question, I need to find the value of "I". Thanks

No angles were given; they just point away from the first arrow

Homework Statement Question shows one arrow with 10 amperes heading in one direction, which splits into three different pathways. having two labels of 4 and 6 amperes. Homework Equations To be honest I don't know what equations I would use; the courseware really wasn't much help...

Homework Statement Add each set of vectors by using the scale diagram C=28km 20 degrees north of east; D=34 km 30 degrees west of north Homework Equations The Attempt at a Solution Attempted to create a triangle with a right angle; then Pythagorean

Homework Statement Find the magnitude and direction of the equilibrant of each of the following foces: a) forces of 32N and 48N acting at an angle of 90 degress to each other b) forces of 16N and 10N acting at an angle of 19 degrees to each other Homework Equations Sine Law, Cosine law, Soh...

Thanks, I got it!

I do believe virtual images can be shown on a screen, but I think the image would be real, because the light comes together or something like that?

Homework Statement You wish to project a slide on a screen. One of the letters on the slide is a p. When you place the slide in the projector, how much the letter look when you insert the slide(as seen from behind the projector)? Explain. a) p b) d c) b d) q Homework Equations How converging...

Thanks for that little thing you did there. I actually did it myself! But thanks for taking the time to read this and reply! = D

Hey guys I'm new here and I'm lookin' for some help as I'm sure a lot of you come here for that reason as well. I did an experiment where I fill a 150 mL half full, place a pencil in the middle and move it sideways until it reaches the side of the beaker. Then I am to draw a ray diagram of what...
