Two pieces of puffed rice become equally charged as they are poured out of the box and into Kirk's cereal. If the force between the puffed rice pieces is a repulsive one and has a magnitude of 4x10" N when the p are 0.03 m apart, what is the magnitude of the charge on each piece?

Is there a picture of a graph or whatever that goes along with this?

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

Yuh yeet honestly idk
