Answer:
 q = 3.6 10⁵  C
Explanation:
To solve this exercise, let's use one of the consequences of Gauss's law, that all the charge on a body can be considered at its center, therefore we calculate the electric field on the surface of a sphere with the radius of the Earth 
           r = 6 , 37 106 m
           E = k q / r²
           q = E r² / k
           q =  
           q = 4.5 10⁵ C
Now let's calculate the charge on the planet with E = 222 N / c and radius 
            r = 0.6 r_ Earth
            r = 0.6 6.37 10⁶ = 3.822 10⁶ m
            E = k q / r²
             q = E r² / k
             q =  
             q = 3.6 10⁵  C
 
        
             
        
        
        
Answer:
1.7323
Explanation:
To develop this problem, it is necessary to apply the concepts related to refractive indices and Snell's law.
From the data given we have to:



Where n means the index of refraction. 
We need to calculate the index of refraction of the liquid, then applying Snell's law we have:



Replacing the values we have:


Therefore the refractive index for the liquid is 1.7323
