The weight of an object is the force with which it is pulled towards the center of the Earth due to gravity. On the surface of the Earth, the weight of the object is 9 N.

Option 1: The weight would remain the same. This option is incorrect because the question states that the acceleration due to gravity on the new planet is 9 times that on Earth. This means that the force of gravity is stronger on the new planet, so the weight of the object would not remain the same.

Option 2: The weight would be equal to 1 N. This option is incorrect. If the acceleration due to gravity on the new planet is 9 times that on Earth, then the weight of the object would be greater than 1 N.

Option 3: The weight would become 9 times. This option is correct. Since the acceleration due to gravity on the new planet is 9 times that on Earth, the weight of the object would also be 9 times. Therefore, the weight would become 9 N.

Option 4: The weight will be reduced to 1 N. This option is incorrect. As mentioned earlier, if the acceleration due to gravity on the new planet is 9 times that on Earth, the weight of
