Determine the angle and the magnitude of force f so that the resultant force acting on the post is directed vertically upward and has a magnitude of 750 n

The force F = 318 and the angle 18.5°. The first thing to do is to resolve the forces into components along the x and y-axis and then equate it to Rx and Ry. R has no component along the x-axis since it is directed along the y-axis.

Explanation:

The detailed solution can be found in the attachment below. Thank you for reading.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
