Question

If a body weighs 200N on the surface of the Earth, how much will it weigh halfway down to the center of the Earth?

(a) 100N

(b) 150N

(c) 200N

(d) 250N

Answer 1

The weight of an object halfway down to the center of the Earth will be half of its weight on the surface of the Earth.

Step-by-step explanation:

The weight of an object halfway down to the center of the Earth will be half of its weight on the surface of the Earth. This is because weight is directly proportional to the distance from the center of the Earth. Since halfway to the center is half the distance, the weight will be half as well.

So, if the body weighs 200N on the surface of the Earth, it will weigh 100N halfway down to the center of the Earth. Therefore, the answer is (a) 100N.
