Electric field Due to A Point Charge

 Electric field Due to a Point Charge 

Formula 

E = k * q / r^2


Where: 

E = Electric field

k = Coulomb's constant (approximately 8.99 x 10^9 N m^2 C^-2)

q = Charge of the point charge

r = Distance from the point charge


 Key Points: 

1. Radial direction: Electric field lines radiate outward from positive charges and inward toward negative charges.

2. Inverse square law: Electric field strength decreases with the square of the distance.

3. Vector quantity: Electric field is a vector quantity.


 Applications: 

1. Understanding charge interactions

2. Calculating forces on charges

3. Analyzing electric field patterns


Some examples related to electric field due to a point charge:


1. Positive Point Charge: Electric field lines radiate outward from a positive point charge.

2. Negative Point Charge: Electric field lines converge inward toward a negative point charge.

3. Distance and Field Strength: As distance from a point charge increases, electric field strength decreases.

4. Charge Magnitude: Increasing the magnitude of the point charge increases the electric field strength.

Continuous Charge Distribution

 Continuous Charge Distribution  A continuous charge distribution refers to a system where charge is spread over a region, such as a line, surface, or volume. The electric field due to a continuous charge distribution can be calculated using integration. Types of Continuous Charge Distributions: 1. Linear Charge Distribution: Charge is distributed along a line. 2. Surface Charge Distribution: Charge is distributed over a surface. 3. Volume Charge Distribution: Charge is distributed throughout a volume. Formula: The electric field due to a continuous charge distribution is calculated using the formula: E = ∫ dE Where:  dE = Electric field due to a small element of charge  Applications:  1. Calculating electric fields: For complex charge distributions. 2. Understanding charge behavior: In various systems, such as capacitors and conductors. Some examples of continuous charge distributions: 1. Uniformly Charged Rod: Calculate the electric field at a point on the axi...
