A proton, which moves perpendicular to a magnetic field of 0.60 T in a circular path of radius 0.080 m, has what speed? (qp = 1.6  10-19 C and mp = 1.67  10-27 kg)
 a. 9.2  106 m/s
  c. 9.6  106 m/s
  b. 4.6  106 m/s
  d. 3.4  106 m/s

Question 2

An ideal fluid, of density 0.90  103 kg/m3, flows at 12 m/s through a level pipe with radius of 0.50 cm. The pressure in the fluid is 1.3  105 N/m2 . This pipe connects to a second level pipe with a radius of 1.5 cm. Find the speed of flow in the second pipe.
 a. 54 m/s
  c. 0.67 m/s
  b. 1.3 m/s
  d. 0.33 m/s
