The answer is B. Unbalanced force
GPE=mgh
=25 x 10 x 3
=750J
Answer:
a = 9.94 m/s²
Explanation:
given,
density at center= 1.6 x 10⁴ kg/m³
density at the surface = 2100 Kg/m³
volume mass density as function of distance
r is the radius of the spherical shell
dr is the thickness
volume of shell
mass of shell
now,
integrating both side
we know,
a = 9.94 m/s²
okay this is kinda easy
