Please help me to answer the following question.

Instructions:

Using the formula to calculate the Intensity of the Electric field given calculate the intensity of the electric field at a point that is 120 cm (1.2 m) from the electric charge of 1nC (Show your calculations).

E_calculated = _____________________

From the following Graph please find the value of the electric field at a distance of 120 cm from the electric charge.

E_graph = ______________________

Where: E is the Electric field K'is the Coulomb constant g1 is the electric charge r is the distance from the electric charge to the sensor
