An electron is located on the x ‑axis at x0=−2.05×10−6 m . Find the magnitude and direction of the electric field at x=2.77×10−6 m on the x ‑axis due to this electron.

The  value is  

Explanation:

From the question we are told that

   The initial position of the electron  

     The  position that is  considered

Generally the electric field is mathematically represented as

Here k is the coulombs constant  with value  

r is  the distance covered which is mathematically represented as

So

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

this means that the temperature of both substances will be equal
