Electrostatics Question 728
Question: A point charge +Q is positioned at the center of the base of a square pyramid as shown. The flux through one of the four identical upper faces of the pyramid is
Options:
A) $ \frac{Q}{16{\varepsilon _{0}}} $
B) $ \frac{Q}{4{\varepsilon _{0}}} $
C) $ \frac{Q}{8{\varepsilon _{0}}} $
D) $ 0 $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Flux going in pyramid $ =\frac{Q}{8{\varepsilon _{0}}}. $
Which is divided equally among all 4 faces.
$ \therefore $ Flux through one face$ =\frac{Q}{8{\varepsilon _{0}}} $
