At a site where the earth's magnetic field has a magnitude of 0.55 gauss (where 1 gauss = 1.00 10-4 t) and points to the north, 68° below the horizontal, a high-voltage power line 152 m in length carries a current of 120 a. determine the magnitude and direction of the magnetic force exerted on this wire, if the orientation of the wire and hence the current is as follows.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
