# Force of attraction btw two point charges Q and -q separated by d metre is F when these charges are placed on two identical spheres of radius R=0.3d whoese centre are d metre apart the force of attraction btw them is

F$Fe=k*Q*-Q/d^2 F=k*Q*-Q/1.6d^2 F=Fe/1.6 Less than Fe$ therefore the force is less than the force on the two point charges
