If *name* specified, but *force* equals `null`, then the force with *name* will be removed:
To remove the force with the given *name*, pass null as the *force*. For example, to remove the charge force:
```js
var simulation = d3.forceSimulation(nodes)
.force("charge", d3.forceManyBody())
simulation.force("charge", null) // now it is removed
simulation.force("charge", null);
