For a point charge, the graph between electric field versus distance is given by :
Electric field lines contracts lengthwise, It shows
repulsion between same charges
Attraction between apposite charges
No relation between force & contraction.
Electric field lines does not moves on straight path.
Identical charges A, B, and C are located between two oppositely charged parallel plates, as shown in the diagram below. The magnitude of the force exerted on the charges by the electric field between the plates is
least on A and greatest on C
the same on A and C, but less on B
the same for A, B, and C
greatest on A and least on C
What is the magnitude of the electric field intensity at a point where a proton experiences an electrostatic force of magnitude 2.30 x 10-25 newton?
1.44 x 10-6 N/C
1.44 x 1044 N/C
3.68 x 10-44 N/C
3.68 x 106 N/C
The diagram above shows a point, P, located midway between two oppositely charged parallel plates.
If an electron is introduced at point P, the electron will
accelerate toward the negatively charged plate
travel at constant speed toward the negatively charged plate
travel at constant speed toward the positively charged plate
accelerate toward the positively charged plate
