First off, you need to detect _which_ object you clicked on. You can do that by iterating through your spawned objects and do a simple [radius check](https://forum.defold.com/t/detecting-click-zone-on-game-object-like-gui-pick-node-solved/1684/2) since you are using spheres.

When you have that object, you can send the force to it. E.g.

```lua
local object_hash = factory.create( ... )
...
msg.post(msg.url(nil, object_hash, "collisionobject"), "apply_force", {force = ... })

```
