Two point charges + 8 q and – 2q are located at x = 0 and x = L respectively. The location of a point on the x axis at which the net electric field due to these two point charges is zero is:
Text Solution
Verified by ExpertsThe correct answer is:
C
Suppose that a point B, where net electric field is zero due to charges 8q and -2q.
According to condition 
Thus, at distance 2L from oxigin, net electric field will be zero.
