Answer:
 q = 2.65 10⁻⁶ C
Explanation:
For this exercise we use Coulomb's law
         F = 
 
In this case they indicate that the load is of equal magnitude
        q₁ = q₂ = q
the force is attractive because the signs of the charges are opposite
        F =  
        q =  
we calculate
         q =  
         q =  Ra 7 10-12
Ra 7 10-12
         q = 2.65 10⁻⁶ C

The critical angle formula should be: sin^-1(1/n) 
 where "n" is 1.501 into the air
<span>The critical angle of light travelling from benzene, happens because the larger angles of incidence from the inside of the benzene has experienced the total internal reflection. </span>
