COMEDK · Physics · 5. Laws of Motion
A student unable to answer a question on Newton's laws of motion attempts to pull himself up by tugging on his hair. Me will not succeed
- A as the force exerted is small
- B the frictional force, while gripping is small
- C Newton's law of inertia is not applicable to living beings
- D as the force applied is internal to the system
Answer & Solution
Correct Answer
(D) as the force applied is internal to the system
Step-by-step Solution
Detailed explanation
According to Newton's law, the state of an object can be changed by applying external force on it. In given case the force applied is internal, so he will not succeed.
