Electric field is given as

r = 15/2 = 7.5cm = 0.075m
The electric field at their midpoint due to
is:

= 
The electric field at the midpoint due to
is:

= 
The net electric field will be:
E =
+ 
E =
+ 
E = 0 N/C
Answer:
Your answer should be B. Cooled air
Explanation:
I think that would be the moon
"too small to clear objects that are in its orbital path" , which means that it probably not a planet.
hope this helps
