Answer:
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth.
The answer is <span>5.2 × 10-2 newtons.
To calculate this, we will use Coulomb's Law:
</span>F =

where F is repulcive force, k is constant, Q is charge, r is distance between charges.

=

= 1.2 ×

C²
r = 5.0 ×

C²
k = 5.0 ×

Then:
