Auniform solid sphere has a moment of inertia i about an axis tangent to its surface. what is the moment of inertia of this sphere about an axis through its center?

a) 7/5 i
b) 3/5 i
c) 2/5 i
d) 1/7 i
e.2/7 i

option E

Explanation:

given,

I is moment of inertia about an axis tangent to its surface.

moment of inertia about the center of mass

.....(1)

now, moment of inertia about tangent

...........(2)

dividing equation (1)/(2)

the correct answer is option E

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
