Answer:
Decomposers
Explanation:
Decomposers are organisms that gives the soil essential nutrients for new plants to grow.
These are micro-organisms that takes up dead and decaying organisms. They break and reduce them down into useful soil organic matter.
Organic matter are the remains of plants and animals that are very vital in the soil. They provide nutrients needed for plant growth.
Complex organic molecules are broken down into simple and useful ones which are needed for the growth of plants.

Answer:
6.20×10⁴ V/m
Explanation:
The magnitude of electric field is:
E = √(Eₓ² + Eᵧ²)
where Eₓ = ∂φ/∂x and Eᵧ = ∂φ/∂y.
φ = 1.11 (x² + y²)^-½ − 429x
Eₓ = -0.555 (x² + y²)^-(³/₂) (2x) − 429
Eᵧ = -0.555 (x² + y²)^-(³/₂) (2y)
Evaluating at (0.003, 0.003):
Eₓ = -44034 V/m
Eᵧ = -43605 V/m
The magnitude is:
E = 61971 V/m
Rounded to three significant figures, the strength of the electric field is 6.20×10⁴ V/m.
As we know that electrostatic force between two charges is given as
here we know that electrostatic repulsion force is balanced by the gravitational force between them
so here force of attraction due to gravitation is given as
here we can assume that both will have equal charge of magnitude "q"
now we have
now we have
