The electric field strength is defined as the ratio of electric force and charge. The electric field strength will be 2.8 ×10⁵ N/C.
<h3>What is electric field strength?</h3>
The electric field strength is defined as the ratio of electric force and charge. The field's direction is determined by the direction of the force acting on the positive charge.
A positive charge produces a radially outward electric field, whereas a negative charge produces a radially inward electric field.
The given data in the problem is;
Q is the charge= 6. 4 × 10–7 C
E is the electric force=1. 8 × 10–1 N
The relation between the electrostatic force and the electric field due to a charge is given as:

Hence the electric field strength will be 2.8 ×10⁵ N/C.
