Electrostatics Question 726
Question: Two point dipoles $ p\hat{k} $ and $ \frac{P}{2}\hat{k} $ are located at (0, 0, 0) and (1m, 0, 2m) respectively. The resultant electric field due to the two dipoles at the point (1m, 0, 0) is
Options:
A) $ \frac{9P}{32\pi {\in _{0}}}\hat{k} $
B) $ \frac{-7P}{32\pi {\in _{0}}}\hat{k} $
C) $ \frac{7P}{32\pi {\in _{0}}}\hat{k} $
D) $ \frac{6P}{{\in _{0}}}\hat{k} $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] The given point is at axis of $ \frac{{\vec{p}}}{2} $ dipole and at equatorial line of $ \vec{p} $ dipole so that field at given point is
