ADLC Assignment Booklet 4 Forces & Fields 3 2. A particle has a charge of -5.00 JC. At a point near this particle, the electric field strength is 7.2x10' N/C. Determine the distance from this point to the charged particle. 4 3. Point P is collinear with a +2.80 JC charged particle and a -8.50 uC charged particle as shown in the following diagram. Point P is 10 cm to the left of the positive charge and 20 cm to the left of the negative charge. What is the electric field at point P? Point P 10 cm 10 cm +2.80 HC -8.50 HC
