    Calculating Force (magnitude and direction) on a proton

    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...

    Questions on Lenses: Projecting a Slide on a Screen

    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?

    High School How do I create a ray diagram for refraction using a beaker and pencil?

    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...
