The bubble chamber image on the right in Figure Q20.13 (image 2) shows three particles emanating from a point marked with a red near the top of the image. The bubble chamber is in a magnetic field oriented so that the field lines point out of the page. (a) Identify the sign of the charge on each particle. (b) Rank the initial speeds of the particles from least to greatest. How do you know? Assume the particles all have the same mass and charges of the same magnitude.
