Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 13.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.4 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location

What color of light must blue light mix with to create white light? a. yellow b. white c. blue d. green

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?
