An infinitely long insulating cylinder of radius R has a volume charge density that varies with the radius as given by the following expression where rho0, a, and b are positive constants and r is the distance from the axis of the cylinder. rho = rho0 a − r b Use Gauss's law to determine the magnitude of the electric field at the following radial distances. (Use the following as necessary: ε0, rho0, a, b, r, and R.)

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
