Two electrically charged particles, having charges of different magnitude when placed at a distance ‘d’ from each other experience a force of attraction ‘F’. These two particles are put in contact and again placed at the same distance from each other. What is the nature of force between them now?

Actually when they come in contact , there will be redistribution of charge . now the sign of two charge is not given. So it will be difficult to find the nature of force between them.
 
For example if one charge has +6c and other has - 12 c charge , after their contact the net charge on two bodies will be -6c and this charge will redistribute on two particles equally( as we are  assuming that two particles are of identical size). So both particles have -3c each.
