A charged wire of negligible thickness has length 2L units and has a linear charge density λ. Consider the electric field E⃗ at the point P, a distance d above the midpoint of the wire.

The electric field at point P is

Explanation:

Given that,

Length = 2L units

Linear charge density = λ

We need to calculate the electric field at point P

Using formula of electric field

Put the value into the formula

Hence, The electric field at point P is

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
