Electric charge is transferred to an irregular metallic disk as shown in the figure. If 
and 
are charge densities at given points then, choose the correct answer from the options given below:
B and C Only
A and C Only 
D and E Only
(E)
A, B and C Only
Text Solution
Verified by ExpertsD
Therefore, the relationship between charge density and ROC at different points can be expressed as:
From this, the relationship between the charge densities at the specified points becomes clear:
This implies:
Thus, the charge density is greatest at the point with the smallest ROC and decreases as the ROC increases, keeping in mind that 
and 
have equal ROC, hence equal charge densities.
