Q: Briefly answer each of the following questions in 2-3 sentences. i) Do electric

1) yes the electric field lines point along the trajectory of moving particles that are positively charged because direction of electric field is the direction of electric force experienced by a unit positive charge 2) the electric force acting on electron is vertically upward the electric force acting on proton is vertically downward 3) the dielectric increases the capacitance so the energy stored also increases

Question

Briefly answer each of the following questions in 2-3 sentences.

i) Do electric field lines point along the trajectory of moving particles that are positively charged? Why or why not?

ii) An electron and a proton are released in a region of space where the electric field is vertically downward. How do the electric forces acting on the electron and proton compare?

iii) Does inserting a dielectric into a charged and isolated capacitor increase or decrease the energy stored in the capacitor? Explain your answer.

Explanation / Answer

yes the electric field lines point along the trajectory of moving particles that are positively charged

because direction of electric field is the direction of electric force experienced by a unit positive charge

the electric force acting on electron is vertically upward

the electric force acting on proton is vertically downward

the dielectric increases the capacitance so the energy stored also increases
