|
a) |
The solid sphere |
b) |
The hollow sphere |
|
c) |
The disc |
d) |
All will achieve the same kinetic energy |
|
(b) For all the bodies, torque is the same Now , Linear velocity ‘ Therefore, the more value of moment of inertia implies the lesser kinetic energy Among all, the hollow sphere has the maximum moment of inertia, |
’ is the same for all as the same force acts on them
Next Question :
A sphere is moving towards 
-axis with a velocity 
and rotates clockwise with angular speed 
as shown in Figure such that 
. The instantaneous axis of rotation will be

On point |
c) |
Inside the sphere |
d) |
Outside the sphere |
