If two forces are spplied in opposite direction and it's magnitude is also equal thrn resultant force is 0.
So, Let F1=10N
F2=-10N
Hence, resultant force=10+(-10)
=0

Please please please please please please please please please please....
i am not satisfied
what you want now
tell me I'll edit the answer
please explain in short
because when 10 newton fan is joint to roof then resultant force is 10newton but here roof is also pulling the fan with 10newton
srashti is right....we can add only those two forces which act on same body....if two children apply equal and opposite forces on two difference foofballs....would the two forces cancill
in case of fan.....earth pulls fan by say 10 N down and roof pulls fan 10 N up...as both forces act on fan u r allowed to add them and ans. is zero and you see fan at rest happily
now we can come to roof seperately....fan exerts 10 N down on roof...walls react 10 N up on roof....gravity acts 9999(say) down on roof.....as all forces r acting on roof u can add...as roof is happily at rest one thing is clear sum of all these is zero
hope you wont add forces on fan and on roof they r different things....pickle of forces
