Two ice-hockey players simultaneously strike a puck with their sticks. the stick of one player exerts an eastward force on the puck of 12 n. the other player’s stick exerts a northward force of 15 n on the puck. assuming that there is no frictional force between the puck and the ice, what is the magnitude of the net horizontal force on the puck?

Fn= 19.21 N

Explanation:

Forces acting on the puck

F₁ = 12 N  eastward : Force exerted by the first player's stick

F₁ = 15 N  northward :  Force exerted by the second player's stick

Magnitude of the net horizontal force on the puck (Fn)

We apply the formula to calculate resulting forces in rectangular or perpendicular coordinates :

Fn= 19.21 N

small = small current large mag large current

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
