Electrostatics Question 106
Question: Two conducting spheres of radii 5 cm and 10 cm are given a charge of $ 15\mu C $ each. After the two spheres are joined by a conducting wire, the charge on the smaller sphere is [AMU (Engg.) 2001]
Options:
A) $ 5\ \mu C $
B) $ 10\mu C $
C) $ 15\mu C $
D) $ 20\mu C $
Show Answer
Answer:
Correct Answer: B
Solution:
Charge on smaller sphere = Total charge $ ( \frac{r _{1}}{r _{1}+r _{2}} )=30( \frac{5}{5+10} )=10\mu C $
