Thereof, how do you calculate attraction?
Calculate the force of attraction according to F = k * q1 * q2 / d2.
Keeping this in view, what is the formula for net force?
When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN.
