The green houses gases are as follows
,Carbon diaoxide,water vapor ,,Carbon diaoxide ,Methane ,,Carbon diaoxide oxide,CFCs ,ozone.
So the option c is correct.
Answer:
Force between two identical conducting ball will be
Explanation:
We have given there is two identical conducting small spheres having charge
and 
Distance between centers of the ball is 0.290 m
So r = 0.290 m
We have to fond the electric force between the balls
According to Coulomb's law force between two charges is given by

So force 
So force between two identical conducting ball will be
