What is the speed in a vacuum of red light that has a wavelength of 675 nanometers (nm)?

f is prop to m1xm2 double m1 double force

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
