Question

The weight of a body kept at a distance of 6400 km from the centre of the

earth is 10N. What will be the weight of another object kept at a distance of 12,800km ?​

Answer 1

2.5N

Step-by-step explanation:

since force is inversely proportional to square of the distance apart. that means the ratio of distance apart. so u have 12800×12800÷(6400××6400)=4/1

so the weight will be reduced to 1/4 of 10N
