Answer:

Explanation:
The magnitude of the electrostatic force between two charged objects is

where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two charges
The force is attractive if the charges have opposite sign and repulsive if the charges have same sign.
In this problem, we have:
is the distance between the charges
since the charges are identical
is the force between the charges
Re-arranging the equation and solving for q, we find the charge on each drop:

Grass is a producer. It gets its energy from the sun, which i might add is by a process called,"photosynthesis", meaning the grass makes its own food. With this bew energy an animal such as a rabbit comes to eat it, that energy that the grass collected is now the rabbits.
