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

Answer:
1.43m
Explanation:
Given data
m1= 50kg
m2=70kg
We are told that Sally m1= 50 sat at one end which is 2m from the center
Hence, the summation of clockwise moment = summation of anticlockwise moment
See the attached image for your reference
50*2= 70*x
100= 70x
x= 100/70
x=1.43m
Hence the mass m2 will be at the 1.43m mark for the net torque to be zero
