What does set a / b mean I haven't done Math for a long time, a = [- 2,1] B = (0,2) What do you mean by a / b? Is it asking a to dig out B? AUB is the sum of two?? Anb is the overlap of two, right What's a / b???? I don't know what it means The problem is to find a / b
#A ∪ B the combination of set a and set B
#A ∩ B the intersection of set a and set B
#The subset of all the elements not belonging to set B in set a and B
Therefore, A-B is [- 2,0]

On the derivation of Coulomb's law It is said in the book that Coulomb's electric pendulum experiment is more powerful than the torsion pendulum experiment in proving the inverse square law, but how Coulomb deduces the relationship between Coulomb force and R through the relationship between the pendulum period T and the distance r between two charge spheres? It is best to list the relevant derivation formula, thank you!
