A small child tries to moves 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

Options

  1. Athe resultant of the pushing force ( F ), weight of the toy, normal force by the ground on the toy and the fri
  2. Bthe normal force by the ground is equal and opposite to the weight of the toy
  3. Cthe pushing force ( F ) of the child is balanced by the equal and opposite frictional force
  4. Dthe pushing force ( F ) of the child is balanced by the total internal force in the toy generated due to defor

Correct answer

A. the resultant of the pushing force ( F ), weight of the toy, normal force by the ground on the toy and the fri

Step-by-step solution

F _ ext =0 a _ system =0
