The Electric field is measured in N/C. Solved Examples Example 1 A force of 5 N is acting on the charge 6 μ C at any point. Determine the electric field intensity at that point. Solution Given Force F = 5 N Charge q = 6 μ C Electric field formula is given by E = F / q = 5N / 6×10 −6 C E = 8.33 × 10 5 N/C. An electric field is a physical field produced by electrically charged objects, influencing the force and motion of other charged objects. Learn about the electric field in physics: clear definition, simple formula (E = F/q), important points, and real-life applications. Perfect for Class 10 stu. Learn about electric field , a fundamental idea in physics that explains the forces of attraction or repulsion between charges. Find formulas for electric field intensity due to point, line, surface and volume charges, as well as electric dipole and electric field lines.
