Question

PLEASE do this physics question. I will mark you as brainliest if solution is exact.

Answer 1

mass of body = 25kg
weight on earth = mg
= 25 × 10 = 250N
mass on other planet = 25 kg bcoz mass is same everywhere
g at planet = GM/R^2
= G×2M/(R/2)^2
= (GM/R^2) ×8
=10×8
=80
Weight on planet= mg
=25×80. =. 2000N

Answer 2

Here,

We have to use the formula force = mass * acceleration

F = ma
We have to find the weight on Newton scale

It's given that m = 25
And a = g = 10m/s²

Therefore
F = 25*10
F = 250

Therefore the weight of the body in earth in Newton scale is 250 newton

Now,
We have to use the formula
F = G*d*D/r²
=Gm/r²
=80

Now the weight = 80 *25 = 2000
