Two electric charges 
and 
are placed 20 cm apart in air. There will be a point P on the line joining these charges and outside the region between them, at which the electric potential is zero. The distance of P from 
charge is
Text Solution
Verified by ExpertsThe correct answer is:
C
Point P will lie near the charge which is smaller in magnitude i.e. – 6 μ μ C. Hence potential at P
⇒ ⇒ x = 0.2 m
