Electric Field is the region produced by an electric charge around it whose influence is observed when another charge is brought in that region where the field exists.
The force F experienced by electric charge q describes the Electric field lines.
The Electric Field formula is expressed by
If q and Q are two charges separated by distance r, the Electric force is given by
When we substitute the electric force formula in the electric field formula, we get Electric Field Formula which is given by,
If the Voltage V is supplied across the given distance r, then the electric field formula is given as
The Electric field is measured in N/C.
A force of 5 N is acting on the charge 6 μ C at any point. Determine the electric field intensity at that point.
Force F = 5 N
Charge q = 6 μ C
Electric field formula is given by
E = F / q
= 5N / 6×10−6C
E = 8.33 × 105 N/C.
