Why does the gravitational force between Earth and Moon predominate over electrical forces?
PHYS 242 BLOCK 1, PART 2, NOTES Sections 22.2 to 22.5 Theelectric fΦExthrough a surface is related to the electricfield lines. Although we can draw as many electric field lines as we want to represent the electric field, the electric flux has a definite value. → Special case 1.If E is uniform (that is, constant in both magnitudflat surface of areaA is → N·m 2 perpendicular to E as shown in Fig. 2Φ.E= EA (in C ).
