Please I need help to solve this problem. Please use the following link:

Working on the simulation: https://phet.colorado.edu/sims/html/charges-and-fields/latest/charges-and-fields_en.html

Instructions:

• Remove the second positive charge you added in previous question (keep the first 1 nC positive charge added).
• Drag 5 sensors and place then 0.5m, 1.0 m, 1.5 m, 2.0 m and 2.5 m from the positive charge. Click on values (top - right corner) and complete the table below.

Sensor # Distance from charge to sensor, Intensity of the Electric Field;.. r E (m) (V/m) 1 0.5 2 1.0 3 1.5 4 2.0 5 2.5
