Question
Choose the correst statement below about the electric field lines for a point charge. 5.AO If the electric field near a point charge points toward that charge, then the charge is positive is smaller than charge B. BO If the density of electric field lines near charge A is larger than near char ge B, then the magnitude of charge A CO If the electrie field near a poiut charge points toward that charge, then the charge is negative DO If the electric ield near a point charge points away from that charge, then the charge is negative. EO If the magnitude of charge A is larger than charge B, then the density of electric field lines near charge A is smaller than near charge B The graph to the right shows the potential V as a function of position x for a non- uniform electric field. In which region(s) is the electric field positive, oriented to the right? 6.AO E and F BO B and C CO A DO C and D EO D The kinetic energy of a proton after it accelerates from rest through a potential differenice of 160 V is (in eV) through 160-loneta 7.AO 400 eV BO 1120 eV CO 16000 ev DO 160 eV BO 720 eV Choose the correct statement below about the uniform electric field shown below 8.AO The plate on the left is negatively charged B?The electrostatic force on a charge is weaker at point C than at point B CO The electrostatic force on a charge is the same at points A and B DO The electrostatic force on a charge is weaker at point B than at point A EO The kinetic energy of a negative charge moved from point C to point A will increase A charge +Q generates a potential of 40 V at a point 1 m away from the charge, with respect to a zero potential reference at infinity. What is the potential at another point 2 m away from the charge? 9.AO 5.0 V BO 80. V 1.6E+02 V DO 3.2E+02 VExplanation / Answer
5) option c.
As electric field lines points towards the negative charge and goes away from positive charges. Also no. Of lines or density of lines is greater for greater charges.
