Question

Write an expression for the force exerted on a test
charge by a continuous charge distribution.​

Answer 1

Answer:

force between the two charged points is directly proportional to the product of these charges and inversely proportional to the square of the distance between them.

\frac{q1 \times q2 }{r {}^{2} }^{2}

hope it helped u.

Answer 2

Answer:

It is referred to as linear charge distribution when the charge is not dispersed equally throughout the conductor's length. It is represented by the Lambda λ  symbol and is also known as linear charge density. There is a linear charge density in mathematics: λ = dq/dl. The linear load density is measured in C/m.

Explanation:

• All the charges are tightly bonded, or there is a very little gap between them, in continuous charge distribution. However, this tightly coupled system does not guarantee that the electric charge remains constant. It is evident that there is a small amount of space between each individual charge's distribution, which is continuous.
• Only point charges are covered by Coulomb's Law, the superposition principle, and electric field expressions. It is exceedingly challenging to examine individual charges in charged bodies when dealing with the electric field caused by a charged sphere, wire, etc. Since the discrete nature of charges is not taken into account here, it is believed that the charge is spread continuously on the charged bodies.
