Two electrons are separated by a distance of 3.00 x 10^-6 meter. What are the magnitude and direction of the electrostatic force
Brilliant_brown [7]
The electrostatic force between two charges q1 and q2 is given by
F=k_e  \frac{q_1 q_2}{r^2}
where 
k_e = 8.99 \cdot 10^9 N m^2 C^{-2} is the Coulomb's constant
r=3.00 \cdot 10^{-6} m is the distance between the two charges.

In our problem, the two charges are two electrons, so their charges are equal and equal to 
q_1=q_2=q=-1.6 \cdot 10^{-19}C

By substituting these values, we find the intensity of the force between the two electrons:
F=(8.99 \cdot 10^9 N m^2 C^{-2})  \frac{(-1.6 \cdot 10^{-19}C)(-1.6 \cdot 10^{-19}C)}{(3.00 \cdot 10^{-6} m)^2}=2.6 \cdot 10^{-17}N

This is the magnitude of the force each electron exerts to the other one. The direction is given by the sign of the charges: since the two electrons have same charge, they repel each other, so the force exerted by electron 1 is toward electron 2 and viceversa.

Velocity is:
Romashka-Z-Leto [24]

Answer:

A

Explanation:

A is correct as Velocity includes the + and - signs, indicating the direction followed by the magnitude which is the speed.

B is Wrong. Velocity is <em>d</em><em>i</em><em>s</em><em>p</em><em>l</em><em>a</em><em>c</em><em>e</em><em>m</em><em>e</em><em>n</em><em>t</em><em> </em>divided by time.

C Im not sure, Sorry..

D is wrong. Same explanation as B
