(C) 200 N
Explanation:
The acceleration due to gravity on earth 
is given by
where 
= universal gravitational constant
= mass of the earth
= radius of the earth
Planet Krypton has twice the mass of earth and 3 times the radius so its acceleration due to gravity 
is
or
If we multiply both sides by Superman's mass, we get his weights on both planets:
The gravitational effect of the moon causes both the high tide and low tides.
According to Gauss' law, the electric field outside a spherical surface uniformly charged is equal to the electric field if the whole charge were concentrated at the center of the sphere.
Therefore, when you are outside two spheres, the electric field will be the overlapping of the two electric fields:
E(r > r₂ > r₁) = k · q₁/r² + k · q₂/r² = k · (q₁ + q₂) / r²
where:
k = 9×10⁹ N·m²/C²
We have to transform our data into the correct units of measurement:
q₁ = 8.0 pC = 8.0×10⁻¹² C
q₂ = 3.0 pC = 3.0×10<span>⁻¹² C
</span><span>r = 5.0 cm = 0.05 m
Now, we can apply the formula:
</span><span>E(r) = k · (q₁ + q₂) / r²
= </span>9×10⁹ · (8.0×10⁻¹² + 3.0×10⁻¹²) / (0.05)²
= 39.6 N/C
Hence, <span>the magnitude of the electric field 5.0 cm from the center of the two surfaces is E = 39.6 N/C</span>
Answer:
I think the the answer is creating and layout and template style ( C )

I did it before and i was checking my notes and i wrote that down , Hope this Helps :)
