Please answer the following questions and show how. The answers of each question are in brackets at the end of each question, thank you so much!

1.) Two small electrified objects A and B are separated by 0.03 m, and repel each other with a force of 4.0x10*-5 N. If we move body A an additional 0.03 m away, what is the electric force now? (1.0x107-5N) 6.) How many electrons make up a charge of 1.0 MC? (6.24x10*12) 7.) What is the total charge on 1.0 kg of electrons? (1.76x10*11C) 8.) What is the magnitude of the force a 10 charge exerts on a 3.0 mC charge 2.0 m away? (67.5N) 9.) Two charged bodies exert a force of 420mN on each other. What will be the force of they are moved so they are only one-third as far apart? (3.8N) 11.) What is the magnitude of the electric force of artraction between an iron nucleus (q+26e) and its innermost electron if the distance between them is -1.0x10*-12 m? (6.0x10\"-3N) 18.) In one model of the hydrogen atom the electron revolves in a circular orbit around the proton with a speed of 1.1x10%6 m/s. What is the radius of the electron's orbit? (2.1x10*-10m)
