SINCE BOTH THE PARTICLES R OF THE SAME CHARGE.
A PARTICLE SHOULD BE KEPT IN BETWEEN THE PARTICLES AND CLOSER TO THE SMALER CHARGE.
LET THE CHARGE OF THE PARTICLE BE Q
AND SO THE REPULSION FROM THE q CHARGE SHOULD BE = TO THE REPULSION FROM THE 2q CHARGE.
SO
qQ/X^2=2Qq/(D-X)^2
1/X^2=2/(D-X)^2
2X^2=(D-X)^2
2X^2=D^2+X^2-2DX
X^2=D^2-2DX
THEN EQUATE DISTANCE AND FIND Q
SOLVE IT AND ULL GET THE ANSWER
PLZ RATE ME IF U FIND ME USEFUL
!!!!!!!!CHEERS!!!!!!!!!!!!


From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king.
