Katie and jon are in the same accounting class, they live in the same wing of their dormitory, and they usually both study at the campus coffeehouse in the morning before class. over time, katie and jon become attracted to each other. what force is most likely at work here?

Gravitational force

Explanation:

Gravitational force is force of attraction which acts between any two bodies having mass. It is a fundamental force and is the weakest of all the fundamental forces.

Katie and Jon have force of attraction between them  and it is the gravitational force.

Electrostatic force acts between charged particles. It can be attractive or repulsive in nature.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
