Answer: 10 units of Force

Explanation:

Given that :

Two opposite forces applied on a body in different direction :

BOY = 20 units of force = F1

GIRL = 10 units of force = F2

The net force acting on the body is the sum of the forces acting in the body:

Fnet = F1 + F2

Since they are acting in opposite direction:

Fnet = F1 - F2

Fnet = 20 - 10

Fnet = 10 units of Force

The direction of the force will be in the direction in which the greatwr unit of force was applied.

Hence, the direction of the boy

The net force on the object is 10 N in the direction of the boy.

Force is a vector quantity. The resultant of two vectors acting in opposite direction is obtained by subtraction.

Now, the boy exerts a force of 20 N while the girl exerts a force of 10 N on the same crate in opposite direction.

The resultant force experienced by the crate is;

20 N - 10N = 10N

The direction of this resultant force must be the direction of the larger force.

Therefore, the net force on the object is 10 N in the direction of the boy.
