Answer: Fnet = 40 N on the right
Explanation: The net force is the summation of forces acting on an object. Add the forces in the same direction and subtract to the opposing force moving in the opposite side.
Fnet= F1 + F2 - F3
= 120 N + 60 N - 140 N
= 180 N - 140 N
= 40 N on the right

Answer:
The value of the true strain at the onset of the necking is proved as,
Explanation:
From the question we see that necking begins when
Now we are told that
So substituting this into equation 1
But we are told in the question that So,
Dividing both sides with
We have
Kinetic energy of electron is gained by the potential energy that it is getting through the potential applied across it
now here we know that that
charge that is accelerated is an electron
so we will have
here we know that
so kinetic energy will be same as potential energy which is equal to
