Question

An object is placed at a distance of R/2
from the centre
of earth. Knowing mass is distributed uniformly,
acceleration of that object due to gravity at that point is
(g = Acceleration due to gravity on the surface of earth
and R is the radius of earth)
(1) g
(2) 2g
(4) none of these
A1​

Answer 1

Answer:

g/2

Explanation:

Acceleration due to gravity at a depth d from the surface of the earth is given by,

${g}^{.....} = g(1 - \frac{d}{r} )$

Here given d=R/2

Therefore, Acceleration of that object =g/2

Answer 2

Answer:

1

because acc. due to gravity of any body is independent of it's mass and it's distance from the eartj
