Answer:
balanced forces: Equal in magnitude, Opposite in direction, Does not cause any change in the state of motion of the object.
unbalanced forces: Unequal in magnitude, Can be in any direction but opposite, Causes change in the state of motion of the object.
equal: balanced forces do not change in motion, they are equal in size and opposite in direction

Answer:
The path difference between the two waves should be one-half of a wavelength.
Explanation:
For the destructive interference to form at point P the path difference between the two waves should be
= 
where n can be any integer starting from 0,1,2....
therefore we can say that
If the maximum destructive interference is to occur at point P, The path difference between the two waves should be one-half of a wavelength.
