Electrostatics Question 395
Question: Two unlike charges of magnitude $ q $ are separated by a distance $ 2d $ . The potential at a point midway between them is [JIPMER 1999]
Options:
A) Zero
B) $ \frac{1}{4\pi {\varepsilon _{0}}} $
C) $ \frac{1}{4\pi {\varepsilon _{0}}}.\frac{q}{d} $
D) $ \frac{1}{4\pi {\varepsilon _{0}}}.\frac{2q}{d^{2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
Potential at mid point $ O,V=\frac{kq}{d}+\frac{k(-q)}{d}=0 $
