Question

While using Gauss's law to find the E-field due to a point charge, we start with the fact that the electric field is in the radial direction.

(a) We are using Coulomb's law

(b) We are using the fact that all points in space are equivalent

(c) We are using the fact that all directions in space are equivalent

(d) We are using our intuition
​

Answer 1

Answer:

A) a is the correct answer

Answer 2

Answer:

While using Gauss's law to find the E-field due to a point charge, we start with the fact that the electric field is in the radial direction we are using Coulomb's law i.e.option(a).

Explanation:

• Coulomb's law states that the force of attraction or repulsion between two charged bodies is inversely proportional to the square of the distance between them and directly proportional to the product of their charges.
• It operates on the segment connecting the two charges regarded as point charges.
• The relationship between the electric field and electrostatic force directions depends on the sign of the test charge.
• The force and field vectors will point in the same direction if the test charge is positive.
• The force and field vectors will be in the opposite directions if the test charge is negative.

So, while using Gauss's law to find the E-field due to a point charge, we start with the fact that the electric field is in the radial direction we are using Coulomb's law i.e.option(a).
