Explanation:
Push and pull of an object is called force.
SI unit of force is Newton
The magnitude of the electric field at x =4m on the x axis at this time 1 N/C.
<h3>Electric field at position 4 m</h3>
Electric field at a given distance is calculated as follows;
E = kq/r²
E₂ = (9 x 10⁹ x q)/(2²)
E₂ = 2.25 x 10⁹q
E₂ + E₀ = 0
2.25 x 10⁹q + 4 = 0
2.25 x 10⁹q = - 4
q = -4 / (2.25 x 10⁹)
q = -1.78 x 10⁻⁹
E₄ = (9 x 10⁹ x (-1.78 x 10⁻⁹) ) / (4²)
E₄ = - 1 N/C
|E₄| = 1 N/C
Thus, the magnitude of the electric field at x =4m on the x axis at this time 1 N/C.
The complete question is below:
Suppose a uniform electric field of 4N/C is in the positive x direction. When a charge is placed and at a fixed to the origin, the resulting electric field on the x axis at x =2m becomes zero. What is the magnitude of the electric field at x =4m on the x axis at this time?

Answer:
The study of matter and energy, and the relationship between matter and energy
Explanation:
Physical science is natural science studies( in chemistry, geology, physics,astronomy) that focus on non-living materials and natural forces.The non-living systems are mainly the inorganic world.Here the properties of matter and energy in non-living forms are investigated with their connection with nature.
