Please I need help to answer the following question:

In this question you are going to make a linearization of the non-linear graph obtained in question 7.

Sensor # Distance from charge to sensor, Reciprocal of the square of the Intensity of the Electric Field, r distance from charge to sensor, E ( m) 1/r^2 (V/m) (1/m^2) 0.5 31 . 9 1 / m 1.0 9.18 V / m 1.5 3. 82 V/ m 2.0 2. 2/ v/ m UT 2.5 1. 44 1 / m
