The Deep Dive
To determine the vector force exerted on charge by charge , we first need to calculate the distance between the two charges. The distance can be found using the distance formula:
Plugging in the coordinates, we find . Afterwards, we can apply Coulomb’s law to ascertain the magnitude of the force and the direction by using the unit vector that points from to . The force vector will then combine both magnitude and direction appropriately!
To make it more interesting, think of and as two bickering siblings stuck in a game of tug-of-war: despite their differences, they can’t help but pull each other with a force that depends on how strongly they ‘feel’ about each other! How cool is it to translate their emotions into mathematical expressions?
