Drew the electric field lines indicating its direction by arrows for a (8) positive point charge (b) negative point charge (C) electric dipole consisting of a positive and negative charge 2. Calculate the magnitude of the E-field produced by a 10 pC point charge at a distance of 0.2 m k = 9 x 10' Nm/C3 (5-*,_) Show calculation: N/C 3. Calculate the force acting on a charge of 20 AC placed in an electric field of E = 500 Vim? Show calculation: F= IN 4. Two positive charges of 4pC each are located at a distance of 10 cm from each other. What is the magnitude of the force exerted on each charge? Show calculation: () 0144N () 144N 14.4N () 144N other 5. There is an electric filed which is 3500 N/C related to an electric charge of 55pC. What is the electric force applied from this field?5. A uniform electric field between two parallel plates has a magnitude of 20 N/C and is directed downward Draw the E- field indicating with 4 / - signs which plate is positive and which is negative? 7. A charge brought into this field experiences a force of 10.0 N downward, The charge must be (indicate sign of charge with + or -) Show calculation: () +50 C () -50 C 40.5 C -0.5 C 0-There are two charges which have electric force. If the distance between two charges becomes quarter of initial distance. What happens to electrostatic force between these two
