Question: Force of attraction between two point charges \[Q\] and – Q separated by \[d\,metre\] is \[{F_e}\]. When these charges are placed on two identical spheres of radius \[R = 0.3\,d\] whose centres are \[d\,metre\]apart, the force of attraction between them is

1) Greater than \[{F_e}\]

2) Equal to \[{F_e}\]

3) Less than \[{F_e}\]

4) Less than \[{F_e}\]
