(wоrk fоr this questiоn to be uploаded аfter closing lockdown browser in Test1- File uploаd quiz) Two charges are placed along the x-axis. Charge q1 = - 1.5 µC is placed at x= -20 cm, q2 = 5.4 µC is placed at x= 20cm. (positive x to the right) a) Find the electric field (magnitude and direction) due to both charges at x=0. (1 point) b) Find the electric potential due to both charges at x=0. (1 point) c) Qualitatively, at what position could the electric field be zero? i.e. in between charges, to the left of q1, to the right of q2 - Explain with a diagram drawing the electric field due to each charge in each of these locations- no credit without the diagram and/or reasoned explanation.
