It should be true: electrons low from negative toward positive to negative toward positive because opposite charges attract each other.
I hope this was correct
Answer with Explanation:
We are given that


Charge on proton,q=
a.We have to find the electric potential of the proton at the position of the electron.
We know that the electric potential

Where 


B.Potential energy of electron,U=
Where
Charge on electron
=Charge on proton
Using the formula


Mass/volume is density so it’s 562g/72cm^3 so it’s roughly 7.805g per cubic centimeter
Answer:
0.78333 m/s in the opposite direction
1.566 m/s in the same direction
Explanation:
= Mass of penny = 0.0025 kg
= Mass of nickel = 0.005 kg
= Initial Velocity of penny = 2.35 m/s
= Initial Velocity of nickel = 0 m/s
= Final Velocity of penny
= Final Velocity of nickel
As momentum and Energy is conserved


From the two equations we get

The final velocity of the penny is 0.78333 m/s in the opposite direction

The final velocity of the nickel is 1.566 m/s in the same direction
