Two electric dipoles of moment p and 
are placed in opposite direction on a line at a distance of 25 cm. The electric field will be zero at point between the dipoles whose distance from the dipole of moment 
is
A
5 cm
B
C
10 cm
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Suppose neutral point N lies at a distance x from dipole of moment p or at a distance ( 
) from dipole of moment 64 p.
At point 
electric field due to dipole 1
Electric field due to dipole 2
At point 
electric field due to dipole 1
Electric field due to dipole 2
