You have now learned two interpretations of electrical interactions 1) a charge in an electric field feels a force of attraction or repulsion; 2) a charge in an electric field possesses a potential energy. Remove an electron from your body or from one of your group-mates. If you were not able to do so, then you are allowed to just imagine an electron (q = -1.602x10-19 C, mẹ = 9.109 x10-31 kg) is placed in the middle of the electrodes. 1. Compute the magnitude and direction of the electric force F=qE exerted on the electron. 2. Does the electron speed up or slow down under the influence of this force? 3. Based on your conclusion, determine whether the change in the kinetic energy is: i) greater than zero (i.e., an increase); i) less than zero; i) equal to zero? 4, Using the definition of electric potential energy, PEelec = qV, compute the change in potential en- ergy as the electron moves between the electrodes. Is APEelec: i) greater than zero (i.e., an in- crease); ii) less than zero; iii) equal to zero?

Atoms have an equal number of electrons and protons so are electrically neutral. Atoms that have a net electrical charge are known as "ions". Positive ions - have "missing" electrons Negative ions - have "excess" electrons 3. The net charge of an object can be found be summing the individual charges. Since charge is quantized, all net charges are just an integer multiple of the elementary charge. q-ne where q is the net charge and n is an integer. For example, sodium can be a +1 ion and chlorine can be a -1 ion. What does this mean concerning their charge and structure?

Q1
An electron has a force of 4,8 x 10^16 N (towards the left) of an electric field. What is the correct answer for the electric field:a) 1,6 x 10^3 N/C (droite) b) 3,3 x 10^-4 N/C (droite) c) 3 x 10^3 N/C (droite) d) 2 x 10^3 N/C
You are working in a laboratory, using very sensitive measurement equipment. Your supervisor has explained that the equipment is also very sensitive to electrical discharge from human operators. Specification tables for the equipment indicate that an electrical discharge providing even a very small amount of energy of 250 μJ is enough to damage the equipment. Your supervisor wants to install an apparatus that will be used to remove the electrical charge from individuals’ bodies before they touch the equipment. To do this, she asks you to estimate (a) the capacitance of the human body and determine (b) the charge on the body and (c) the electric potential of the body, relative to a point infinitely far away, corresponding to the energy transfer that will damage the equipment.
