1.7 particles with charge q = 4.0 nC are exactly the same. They are placed 30 degrees apart along the

1.7 particles with charge q = 4.0 nC are exactly the same. They are placed 30 degrees apart along the circumference of a circle of radius 2.0 cm, forming a semicircle on the left as shown. Set ke = 9.0 x 109 NmC-2. (a) Find the total electric field at the point center of circle (b) If a particle with a charge of -4.0 C and a mass of 1.0 mg is placed at the center of a circle, How will this charged particle move? With how much acceleration? (Writing a free body diagram will help you see the big picture. Forces and fields are vector volumes. Find both size and direction) y
