Find the correct option.

Answer to Problem 1RQ

The correct option is (d). “All of the above”.

Explanation of Solution

Calculation:

Force has magnitude as well as direction. Therefore, it is a vector quantity.

Weight of any object is the gravitational force acting on the body. Not all the forces acting on the body is the weight. There are other forces acting on the body that is the frictional force, the force exerted during push or pull and so on.

Force is responsible for causing motion, changing the motion of the object and preventing the object from changing its motion. However, it is not necessary that all the forces produce acceleration and cause motion. For example, if we push a wall, there will not be any motion even though we are applying a force on the wall.

Therefore, all the given options are satisfied.

Conclusion:

Hence, the correct option is (d). “All of the above”.
