The moment of inertia of a spherical shell is I = mr²
If two spheres have the same moment of inertia, then
I₁ = I₂
m₁(r₁)² = m₂(r₂)²
Solve for the second mass:
m₂ = m₁ (r₁/r₂)²
Given m₁ = 1 kg, r₁ = 2 m, r₂ = 1m,
m₂ = (1 kg) (2 m / 1 m)² = 4 kg

Answer:
A) 
Step-by-step explanation:
With respect to our angle, the side opposite to it is
, and the hypotenuse is
, so the trig ratio we need to use here is sine as
. Hence, if we rearrange the equation so that we solve for the opposite side
, then we'll have
as the correct equation.
