Question1

A cylindrical distribution of charge ρ =α/(sprt)r
where α = 2 µC/m^5/2 extends from 0 cm to 9.6 cm . Concentric with this is the dielectric shell with 5.53 of inner radius 17.7 cm and outer radius 24.1 cm.

What is electric ?eld at 12 cm?
Answer in units of V/m

What is electric ?eld at 20.7 cm?
Answer in units of V/m

What is electric ?eld at 38.3 cm?
Answer in units of V/m

Question2

For the charge configuration, let l=40.0cm, q2=q3=-8.00µC, and q1=12.0µC.

a) Find out electric field at the location P

b) If charge of 3.0µC is placed at location P, what is magnitude of the Coulomb force on this charge?

Question3

Bob walks 170 souths, then jogs 450 southwest, and afterwards walks 170 in a direction 29 east of north. Utilize either trigonometry or components to find out displacement that will return Bob to his starting point by most direct route. Confer answer as a distance.
