Direction: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion : When astronauts throw something in space, that object would continue moving in the same direction and with the same speed.
Reason : The acceleration of an object produced by a net applied force is directly related to the magnitude of the force, and inversely related to the mass of the object.
- a)Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
- b)Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
- c)Assertion (A) is true but reason (R) is false.
- d)Assertion (A) is false but reason (R) is true.
Correct answer is option 'B'. Can you explain this answer?

Assertion: When astronauts throw something in space, that object would continue moving in the same direction and with the same speed.
Reason: The acceleration of an object produced by a net applied force is directly related to the magnitude of the force, and inversely related to the mass of the object.
The correct answer is option B - Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
Explanation:
Assertion (A): When astronauts throw something in space, that object would continue moving in the same direction and with the same speed.
In space, there is no atmosphere or air resistance to slow down or stop the motion of an object. This means that once an object is set in motion, it will continue moving in the same direction and with the same speed unless acted upon by an external force. This is known as the law of inertia or Newton's first law of motion. So, the assertion is true.
Reason (R): The acceleration of an object produced by a net applied force is directly related to the magnitude of the force, and inversely related to the mass of the object.
The reason given is not a correct explanation of the assertion. The reason talks about acceleration, which is the rate of change of velocity, and its relationship with the magnitude of the force and the mass of the object. While it is true that acceleration is directly related to the magnitude of the force and inversely related to the mass of the object, it does not directly explain why an object thrown in space would continue moving in the same direction and with the same speed. The reason does not provide any explanation for the absence of external forces acting on the object in space.
In space, there is no friction or air resistance to slow down the object's motion. Therefore, the object will continue moving with the same speed and in the same direction unless influenced by external forces such as gravity or collisions with other objects. The reason provided does not address this specific scenario.
Hence, both the assertion and the reason are true, but the reason does not correctly explain the assertion. Therefore, the correct answer is option B.
