at θ=180∘ we see that Fnet=2F0. (a) For the situation corresponding to curve 1 nonconductive walls the bead move Two identical small balls each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless what is that ratio? what is the ratio of the charge of particle C to that of particle B (including sign)? (b) For the situation corresponding to curve 2
