Question

Choose the correct option after reading the statements given -Statement 1 : The forces of action and reaction always appear due to actual physical contact of two bodies. Statement 2 : A particle can move only under the action of a force. (a) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1. (b) Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1. (c) Statement 1 is true but statement 2 is false. (d) Both statements 1 and 2 are false

Answer 1

Answer:

staement 1 is false and statement 2  true

Explanation:

Answer 2

The correct option is option d: Both statements 1 and 2 are false.

The first statement is based on the third law of Newton in Physics.

• According to this law, for every force of action, there is a reaction force that acts with equal magnitude and in opposite direction.
• However, it is not necessary that two objects are in physical contact with each other for action and reaction force.
• For example, the gravitational force is the one that acts from the distance. If a particular object having gravitational force attracts another body which is at some distance, the other body also attracts the first body through its gravitational force. In this case, both bodies are not in contact though force is acting.

The second statement is based on the first law of newton in Physics.

• The particle can keep moving with constant speed if no force is externally acting on it.
• It is incorrect that particles can move only if a force acts on them.
• Statement 1 and statement 2 are based on different laws of physics and are not correlated to each other.
• Hence, option d is correct.
