Well to clarify, when an object is slowing down, theoretically it must hit every velocity between its initial velocity and zero, so it could never stop, it would just slow down forever. There is an infinite number of velocities between an arbitrary velocity and zero. So what is the slowest...
I was wonder what the slowest velocity possible for an object is. According to mathematics, between any two numbers, there are an infinite number of numbers in between, so between a velocity of 0 and any arbitrary velocity there must be an infinite number of velocities. But from common knowledge...
Yes, I did convert everything to standard units.
R_a=.00709m
R_b=.007m
σ=.009 coulombs/m^2
C=Q/V_ba=4(pi)(Epsilon_0)((R_a*R_b)/R_a-R_b))=6.1327e-11F
Surface area of inner sphere =4(pi)(.007^2)=6.1575e-4m2
σ=Q/A so Q=5.5418e-6
U=.5(Q^2/C)=.5((5.5418e-6)^2)/6.1327e-11)=2.504e-4 kJ...
