A small charged particle of mass 9 × 10−6 kg and charge of magnitude −3 × 10−6 C is placed in a chamber in which there is a uniform electric field. If the charge accelerates due north at a rate of 250 m s−2 what is the magnitude and direction of the electric field inside the chamber? (ignore gravitational forces) 24.7 Answer the following: (a) What is the magnitude and direction of the electric field 10 m away from a +0.1 mC charge? (b) What is the magnitude and direction of the electrostatic force on a +1.5 mC charge placed at this point (10 m from the charge in (a))? (c) What is the magnitude and direction of the electrostatic force on a −3.5 mC charge placed at this point (10 m from the charge in (a))?
