A tank contains benzene, which has index of refraction 1.50. A dime is on the bottom of the tank. When viewed at normal incidence the dime appears to be 61 cm below the surface of the benzene. What is the actual depth of the benzene?
 
  What will be an ideal response?

Question 2

A proton beam that carries a total current of 1.3 mA has 10.0 mm diameter. The current density in the proton beam increases linearly with distance from the center.
 
  This is expressed mathematically as J(r) = J0 (r/R), where R is the radius of the beam and J0 is the current density at the edge. Determine the value of J0. A) 25 A/m2
  B) 6.2 A/m2
  C) 12 A/m2
  D) 17 A/m2
