Let us suppose the magnitude of the original coulomb force between the two charged spheres is f. in this scenario, a third sphere touches the grey sphere and the red sphere multiple times, being grounded each touch. if the grey sphere is touched twice, and the red sphere is touched three times, what is the magnitude of the coulomb force between the spheres now?

(a) f/5

(b) f/6

(c) f/8

(d) f/16

(e) f/32

this is what i did on my own:

before we proceed with the quantitative part of this set, let us make sure that you can see the reading of the electronic balance clearly on your screen. what is the reading of the scale right after the red sphere is first charged, and the electrophorus has been replaced on the slab? use the "pause" and the "frame-by-frame-advance" buttons to navigate to the appropriate part in the video.
