Question

QUESTION: Assign four different electric fields to draw.

Field near a positive charge

Field near a negative charge

Field near a positive and a negative charge

Field between two oppositely charged parallel plates

CONDITIONS:

No variable values need to be given

Assign values for q (+2 uC) and for E (1200 N/C).

Assign a value to r (2.5 m)

Assign a value to q (–6 nC)

No variable values need to be given

Assign values to q: A and B (-5 uC), C and D (+10 uC)

Answer 1

1. The positive charge will have electric field emerging from the charge in to space in spherical fashion. As per picture below,

2. The negative charge will have electric field going into the charge from the space in spherical fashion. As per picture below,

3. The positive charge and the negative charge will have electric field emerging from the positive charge into the negative charge with electric field highest strength in between the charges, i.e. electric field lines will be relatively concentrated in the space between the charges. As per the picture below,

4. The positive charge and the negative charged parallel plates will have constant electric field in the space between them. As per the picture below,
