Question

28. Two small conducting spheres of equal
radius have charges + 10°C and - 20uC
respectively and placed at a distance R
from each other experience from F. If
they are brought in contact and
separated to the same distance, they
experience force F2. The ratio of Fito F2
is
a) 1:2
b) 8:1
c) 1:8
d) 2:1​

Answer 1

Answer:

8:1

Explanation:

equal radius have charges \( +10 \mu \mathrm{C} \) and \( -20 \mu \mathrm{C} \), respectively, and placed at a distance \( R \) from each other experience force \( F_{1} \). If they are brought in contact and separated to the same distance, they experience force \( F_{2} \).
