**Assertion (A):** When astronauts throw something in space, that object would continue moving in the same direction and with the same speed.
**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 correct answer is option 'B' - Both A and R are true but R is not the correct explanation of A.
Explanation:
**Astronauts throwing something in space:**
When astronauts throw something in space, the object will continue moving in the same direction and with the same speed unless acted upon by an external force. This is due to the absence of significant forces such as air resistance or friction in space.
**Acceleration and Net Applied Force:**
The acceleration of an object is directly related to the magnitude of the net applied force and inversely related to the mass of the object. This relationship is described by Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass (a = F/m).
In space, when an astronaut throws an object, they apply a force to it. According to Newton's third law of motion, the object exerts an equal and opposite force on the astronaut. As a result, the object accelerates in the direction of the force applied by the astronaut.
**Explanation of the Reason (R):**
The Reason (R) correctly states that the acceleration of an object is directly related to the magnitude of the force and inversely related to the mass of the object. However, it does not provide a direct explanation for why the object would continue moving in the same direction and with the same speed after being thrown in space.
**Conclusion:**
In conclusion, both the Assertion (A) and the Reason (R) are true. However, the Reason (R) does not provide a correct explanation for the Assertion (A). When astronauts throw something in space, the object will continue moving in the same direction and with the same speed due to the absence of significant external forces like air resistance or friction.
**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 correct answer is option 'B' - Both A and R are true but R is not the correct explanation of A.
