An insect is at the bottom of a hemispherical ditch of radius $\displaystyle 1$ m . It crawls up the ditch but starts slipping after it is at height $\displaystyle h$ from the bottom. If the coefficient of friction between the ground and the insect is $\displaystyle 0.75$ , then h is : $\displaystyle \left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$
Official answer
(2)
0.$\displaystyle 20$ m
