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
Text Solution
Verified by ExpertsThe correct answer is:
C
As we know for hemisphere the particle will leave the sphere at height \(h = \frac{2r}{3}\)

\(h = \frac{2}{3} \times 21 = 14\,m\)
but from the bottom
\(H = h + r = 14 + 21 = 35 \text{ metre}\)
