The magnitude of a point charge is 0.189 x 10⁻⁹C.
<h3>Steps</h3>
We have stated that the point charge's electric field is E=2.5 N/C.
Distance from point charge R = 51 cm = 0.51 m
We are aware that the electric field resulting from a point charge is given as E = 1 / 4π∈₀ × Q / R²
so 2.5 = 9 x 10⁹ Q/ 0.68²
The magnitude of a point charge is 0.189 x 10⁻⁹C.
The electric force per unit charge is referred to as the electric field. It is assumed that the field's direction corresponds to the force it would apply to a positive test charge.
From a positive point charge, the electric field radiates outward, and from a negative point charge, it radiates in.

Elastic
☑ occur when the colliding objects bounce off of each other
☑ hard or bouncy objects
☑ kinetic energy is conserved
Inelastic
☑ occur when two objects collide
☑ two objects colliding stick together
☑ kinetic energy is not conserved — some of the initial kinetic energy is converted into other types of energy (heat, sound, etc.)
