A small child tries to move a large rubber toy placed on the ground. The toy does not move but gets deformed under her pushing force $(F)$ which is obliquely upward as shown. Then

Question

Answer 1

According to newton second law
$F = m a$
So

Since there is no acceleration of body , $a = 0$ hence $F = 0$ therefore sum of all forces acting on body must be equal to zero. Therefore sum of pushing force, weight of toy and normal reaction by ground and friction by ground must be equal to zero.

Answer 2

According to newton second law

$F = m a$

So

Since there is no acceleration of body , $a = 0$ hence $F = 0$ therefore sum of all forces acting on body must be equal to zero. Therefore sum of pushing force, weight of toy and normal reaction by ground and friction by ground must be equal to zero.

A small child tries to move a large rubber toy placed on the ground. The toy does not move but gets deformed under her pushing force $(F)$ which is obliquely upward as shown. Then

The resultant of the pushing force $(F)$ , weight of the toy, normal force by the ground on the toy and the frictional force is zero

The normal force by the ground is equal and opposite to the weight of the toy

The pushing force $(F)$ of the child is balanced by the equal and opposite frictional force

The pushing force $(F)$ of the child is balanced by the total internal force in the toy generated due to deformation

According to newton second law
$F = m a$
So

Since there is no acceleration of body , $a = 0$ hence $F = 0$ therefore sum of all forces acting on body must be equal to zero. Therefore sum of pushing force, weight of toy and normal reaction by ground and friction by ground must be equal to zero.

Four alternatives are given to each of the following incomplete statement/question. Choose the right answer.
If the forces acting on an object are balanced then

What happens when some children try to push a box on a rough floor?

(a). Name the forces acting on a plastic bucket containing water held above ground level in your hand.

(b). Discuss why the force acting on the bucket do not bring change its state of motion ?

(c). Why do porters place a round of cloth on their heads when they have to carry heavy loads?

A body is acted upon by two forces, but it does not move.
What can you say about the two forces ?

What are balanced forces ?

A small child tries to move a large rubber toy placed on the ground. The toy does not move but gets deformed under her pushing force (F) which is obliquely upward as shown. Then

The resultant of the pushing force (F), weight of the toy, normal force by the ground on the toy and the frictional force is zero

The normal force by the ground is equal and opposite to the weight of the toy

The pushing force (F) of the child is balanced by the equal and opposite frictional force

The pushing force (F) of the child is balanced by the total internal force in the toy generated due to deformation

According to newton second law F=maSo Since there is no acceleration of body , a=0 hence F=0 therefore sum of all forces acting on body must be equal to zero. Therefore sum of pushing force, weight of toy and normal reaction by ground and friction by ground must be equal to zero.
