Im not to good at geography but I think you are correct :)
Earth is 150 million kilometers away for the sun
Hmmm the only formula i know is v = d * t or volocity = distance * time
The correct diagram is shown below:
The charges of +2 µC and +3 µC are 4 mm from each other. The diagram below represents the electrical force between the charges. i.e. repulsive force. However the force of repulsion exerted by charge +3 µC on +2<span> µC will be more. The same charges repel each other and opposite charges attract each other.</span>
