Several bacteria are propelled by biological motors that spin hair-like flagella. A typical bacterial motor turning at a constant angular velocity has a radius of 1.21 10-8 m, and a tangential speed at the rim of 2.32 10-5 m/s.
1. What is the angular speed (the magnitude of the angular velocity) of this bacterial motor?
2. How long does it take the motor to make one revolution?
-5-nC point charge is located at the center of a conducting spherical shell. The shell has an inner radius of 2 m, an outer radius of 4 m, and a charge of +6 nC. (Let the radially outward direction be positive.)
the electric potential immediately outside another charged conducting sphere is 200 v and 10.0 cm farther from the
