Two infinitely large charged planes having uniform surface charge density \[+\sigma \] and \[-\sigma \] are plane along x-y plane and \[yz\] plane respectively as shown in the figure. Then the nature of electric lines of forces in x-z plane is given by : |
A)
B)
C)
D)
Correct Answer: C
Solution :
The electric field intensity due to each uniformly charged infinite plane is uniform. The electric field intensity at points A, B, C and D due to plane 1, plane 2 and both planes are given by\[{{E}_{1}},\]\[{{E}_{2}}\] and E as shown in figure 1. Hence the electric lines of forces are as given in figure 2. |
Aliter: |
Electric lines of force originate from positively charged plane and terminate at negatively charged plane. Hence the correct representation of ELOF is as shown figure 2. |
