Question

a body wheighs 500N at earth surface. what will be the weight of this body if it is carried to a height equal to the radius of the earth.
ppz help quickly​

Answer 1

Answer:

125N

Explanation:

Weight of body= mg= 500N

So, mass of body,m = 500÷ 10= 50Kg.

At height h, the value of g' is given by,

g' = g R^2/ ( R+h)^2

= 10 R^2 / (R+R)^2

= 10 × 1/4

So, weight at a height h = mg'

= 50 × 10× 1/4

= 125N
