Moment of inertia of a solid sphere about a diameter is 8 g `cm^(2)` (mass = 5 g, radius = 2 cm). Moment of inertia of the solid sphere about a tangent shall be :

Options

A. `28 g cm^(2)`
B. `40 g cm^(2)`
C. `18 g cm^(2)`
D. `12 g cm^(2)`

Answer

A

Explanation

`I_("tangent")=I_("diameter")+mr^(2)=8+5xx2^(2)=28gcm^(2)`
