Question 14 (1 point) An electric motor is powered by a 12 V battery has 220 C of charge passing through it. How much electric potential energy is transferred? O 2600 J ( 18 J 0.055 J 32 000 J Question 15 (1 point) What is the magnitude of the magnetic force acting at an angle of 25 degrees on a current of 1.25 A flowing down 1.30 m of wire in a field that has a strength of 15.0 T ? 10.3 N 609 N 22.1 N 98.1 NQuestion 11 (1 point) Saved The proton and the electron both have mass, so they exert a gravitational force upon each other. They also have charge, so they exert an electric force on each other. The distance between the electron and the proton in a carbon atom is 5.2 x 10-" m, the charge of each is 1.6 x 10-19 C. Calculate the magnitude of the electric force. 3.6 x 10-23 N 9.5 x 10-20 N 3.6 x 10-13 N 8.5 x 10-8 N Question 12 (1 point) A proton (mass of 1.67 x 10 -27 kg and a charge of 1.6 x 10 -19 C) is placed in an electric field and accelerates from rest to a final velocity of 2.0 x 105 m/s over a distance of 0.75 m. What is the strength of the electric field (E)? 280 N/C 5.3 N/C 4000 N/C 350 N/C Question 13 (1 point) A test charge is always considered to be negative. True False
