Question
Two similar very small conducting spheres having charges 40 μC and −20 μC are some distance apart. Now they are touched and kept at same distance. The ratio of the initial to the final force between them is :
Options
A.8 : 1
B.4 : 1
C.1 : 8
D.1 : 1
Solution
Final charge on both spheres = 
μC = 10μC (each) [Distibution by conducting]
= 8 : 1
μC = 10μC (each) [Distibution by conducting] = 8 : 1Create a free account to view solution
