Question

as a ladder leans against a wall it exerts a force on both the wall and ground. what are the two reactant forces on the ladder? (1 point)

$\bigcirc -f_{wall\\ on\\ ladder} \\ and\\ f_{ground\\ on\\ ladder}$

$\bigcirc -f_{wall\\ on\\ ladder} \\ and\\ - f_{ground\\ on\\ ladder}$

$\bigcirc f_{wall\\ on\\ ladder} \\ and\\ f_{ground\\ on\\ ladder}$

$\bigcirc f_{wall\\ on\\ ladder} \\ and\\ - f_{ground\\ on\\ ladder}$

Explanation:

According to Newton's third - law, for every action, there is an equal and opposite reaction. The ladder exerts forces on the wall and ground. The wall and ground in turn exert reaction forces on the ladder. The reaction force of the wall on the ladder is $F_{wall\ on\ ladder}$ and the reaction force of the ground on the ladder is $F_{ground\ on\ ladder}$.

Answer:

C. $F_{wall\ on\ ladder}$ and $F_{ground\ on\ ladder}$
