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 [AIIMS 1995]

• A.          Greater than \[{{F}_{e}}\]      
• B.          Equal to \[{{F}_{e}}\]  
• C. Less than \[{{F}_{e}}\]     
• D.          Less than \[{{F}_{e}}\]
