Which of the following is NOT an illustration of Newton's third law ?a...
Explanation:
Newton's third law states that for every action, there is an equal and opposite reaction. In other words, when one object exerts a force on a second object, the second object exerts a force of equal magnitude in the opposite direction on the first object.
a) Flight of a jet plane:
When a jet plane is flying, the engines push air backwards with a certain force. According to Newton's third law, the air exerts an equal and opposite force on the plane, propelling it forward.
b) A cricket player lowering his hands while catching a cricket ball:
This is NOT an illustration of Newton's third law because it does not involve two objects interacting with each other. The action of the cricket player lowering his hands is not directly linked to any specific reaction force.
c) Walking on the floor:
When a person walks on the floor, their feet push against the floor with a certain force. According to Newton's third law, the floor exerts an equal and opposite force on the person, allowing them to move forward.
d) Rebounding of a rubber ball:
When a rubber ball is thrown against a wall, it exerts a force on the wall. According to Newton's third law, the wall exerts an equal and opposite force on the ball, causing it to rebound.
Conclusion:
The correct answer is option 'B' - A cricket player lowering his hands while catching a cricket ball. This is not an example of Newton's third law because it does not involve two objects interacting with each other.

So hii... Newtons third law says that every action has equal and oppsite reaction now a c d describes this phenomenon correctly but while thinking on b i.e a bowler catching a ball moves his hands backwards is an example of a phenomenon undertaken by momentum because while lowering his hands he is trying to slow down the ball to get a lesser effect of momentum...
