Answer: hello your question lacks the required diagram attached below is the required diagram
answer : Both cars will move backwards and stop due to friction.
Explanation:
Given that both cars are negatively charged, When the wedges are removed both cars will move backwards ( repelling each other ) because they are like poles, and Like poles repel each other. while unlike poles attract each other ( forward movement ) .
The cars will later come to a stop due to frictional forces between the cars and the surface.

5. between the stone and the ground
for a stone at rest on the ground, we have two forces acting on the stone. first is the force on the stone by the earth due to gravity of earth. second is the force applied by the ground in upward direction to balance the force of gravity on the stone.
so first interaction is between earth and stone : earth pulls stone towards it and stone pulls earth towards it by same amount of force.
second interaction is between stone and ground : ground push the stone in upward direction and stone push the ground in down direction by same amount of force.
hence the correct choice is
5. between the stone and the ground
