Question

What is the the mass and weight of body at the centre of earth. If its weigh 30N on the surface of earth​

Answer 1

Answer:

we know that gravitational force of earth is 9.8m/second on the moon surface the gravitational force on moon 1.62m/sec square if it weight 30N on earth we know that f-ma

m=F-a

m=30+1.62

m=18.51

m=18.51kg

Answer 2

Explanation:

Objects on the moon are accelerated at 1.624 m/s2. On Earth they are accelerated at 9.807 m/s2. If you measured a force of 30 Newtons on the moon then you would have

F = ma → m = F/a = 30 N / 1.624 m/s2 = 18.47 kg.

On Earth you would measure

F = ma = 18.47 kg * 9.807 = 181.14 Newtons
