Part 1: Studying nature of equipotential surface due to a positive charge Uncheck 'Electric Field'. Select 'Grid' and 'Voltage'. Drag a positive charge and place it at the center. Remember each charge is InC=1x 10"C . > Drag the voltmeter and put it at 10 cm from the charge. Record the value of potential in the Table below. Click on the pencil icon to draw equipotential surface. Complete the table. Use equation 3 for 'Potential Calculated'. [4 points] D Take a screenshot of your equipotential surface and paste it below the table.
