Electric field worksheet

 

1.   What is the strength of an electric field generated by charge  at a distance of 1 m?

 

 

 

2.   A charge  is at the origin, and a second charge,  is on the y-axis 2 m from the origin.  Find the electric field at a point on the x-axis 2 m from the origin.

 

 

 

 

 

 

Direction

 


 

3.   A charge  is at the origin, and a second charge,  is on the x-axis 0.800 m from the origin.  Find the electric field at a point on the y-axis 0.500 m from the origin.

 

 


4.   A proton and an electron in a hydrogen atom are separated on the average by about   What is the magnitude and direction of the electric field generated by the proton at the position of the electron?

 

 

Field lines point away from positive charge.  So the direction is away from the proton.

 

 

5.   An electric field of  is directed along the positive x-axis.

a.   What is the electric force on an electron in this field?

 

Negative charges experience a force against the direction of the electric field, so direction is along the negative x-axis.

 

 

b.   What is the electric force on a proton in this field?

 

Same magnitude, but positive charges experience a force in the direction of the electric field, so the direction is along the positive x-axis.
