Answer:
The correct answer is the ratio of net force to mass is constant across all objects.
Answer:
0.045 J
Explanation:
The work done on a charge moving through a potential difference is given by

where
W is the work done
q is the charge
is the potential difference
In this problem, we have
q = 0.0050 C is the charge
is the potential difference
Using the formula, we find the work done:

The critical mass of a fissionable material depends upon its nuclear properties (specifically, the nuclear fission cross-section), its density, its shape, its enrichment, its purity, its temperature and its surroundings.
