The net force on the fry is 0.015 N.
Explanation:
We can solve this problem by using Newton's second law of motion, which states that:

where
F is the net force acting on an object
m is the mass of the object
a is its acceleration
In this problem, we have a fry with mass
m = 3 g = 0.003 kg
And its acceleration is

Therefore, the net force acting on the fry is
