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: 37.5 nm
Explanation: speed of light c= 3.00·10^8 m/s.
I use same accuracy to speed of light as it's for frequency.
Frequency f= 8.01·10^15 1/s
Speed c = wavelength · frequency
Wavelength = c/f = 3.745·10^-8 m
