Answer:
The electric force will be 0 N
Explanation:
From the question we are told that
The magnitude of the charge is 
Generally from Coulombs law the electric force between two charges is mathematically represented as

Here r is the distance of separation between that two charges.
Now from the question we are told that the charge is far away from any other charge hence we can say that the distance between the charge and any other charge is 
So

=> 
Hence the electric force will be 0 N
I think the answers are box #1 and #3. It is number one for a fact. However, it depends where the start is at #3.
Answer:
so the speed will increase by 1.44 times then the initial speed if the distance is increased to double
Explanation:
As we know that the air friction or resistance due to air is neglected then we can use the equation of kinematics here

since we released it from rest so we have

so here we have

now if the distance is double then we have

now from above two equations we can say that

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double
Answer:
In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.
Since the baseball is half the weight of the softball, the baseball has to go twice as fast as the softball.
So the best answer would be D
