Q

# Answer please! A solid sphere, a hollow sphere and a ring are released from top of an inclined plane ( (frictionless ) so that they slide down the plane . Then maximum acceleration down the plane is for ( no rolling )

A solid sphere, a hollow sphere and a ring are released from top of an inclined plane ( (frictionless ) so that they slide down the plane . Then maximum acceleration down the plane is for ( no rolling )

 Option 1) Solid sphere Option 2) hollow sphere Option 3) ring Option 4) all same

I think the answer should be a ring

Solid sphere

As we learnt in

Rolling of a body on an inclined plane -

$a= \frac{g\sin \Theta }{1+\frac{K^{2}}{R^{2}}}$

$f= \frac{mg\sin \Theta }{1+\frac{R^{2}}{K^{2}}}$

- wherein

$\Theta$ = Angle of inclination

This is the case of sliding (the plane being frictionless) therefore the acceleration of all the bodies is same $a=g \;sin\theta$

Option 1)

Solid sphere

This is an incorrect option.

Option 2)

hollow sphere

This is an incorrect option.

Option 3)

ring

This is an incorrect option.

Option 4)

all same

This is the correct option.
