Q1. A long hollow cylindrical conductor (inner radius = 2.0 mm, outer radius = 4.0 mm) carries a current of 13 A distributed uniformly across its cross section. A long wire which is coaxial with the cylinder carries an equal current in the similar direction. What is the magnitude of the magnetic field 3.4 mm from the axis?

Q2. A superhero flies 147 m from the top of a tall building at the angle of 33 degrees below the horizontal. What is the vertical component of the superhero's displacement?
