B. Exfoliation. Hope I helped you out bro.
Answer:
A. Electric flux
Explanation:
Electric flux is the rate of flow of the electric field through a given area (see ). Electric flux is proportional to the number of electric field lines going through a virtual surface.
Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C−1). Thus, the SI base units of electric flux are kg·m3·s−3·A−1.
As per given condition we know that vertex angle of the cone is given as
so here we can say that vertex angle will remain constant
so here
now for the volume we can say
also we can say
so here we will have
now for volume flow rate
now plug in all data
Atoms have an overall charge that is neutral because atoms have equal number of positive protons and negative electrons thus they cancel each other out. This always true for atoms that are stable and in equilibrium.
