Question

A particle is kept at rest at the top of a sphere of diameter 42 m. When disturbed slightly, it slides down. At what height ‘h’ from the bottom, the particle will leave the sphere

Options:

A . 14 m

B . 28 m

C . 35 m

D . 7 m

Answer: Option C
:
C

A Particle Is Kept At Rest At The Top Of A Sphere Of Diamete...

As we know for hemisphere the particle will leave the sphere at height h =

\frac{2 r}{3}

h =

\frac{2}{3} \times

21= 14 m
but from the bottom
H = h +r = 14 + 21 = 35 metre
