Questions
An insect crawling up a fixed hemispherical bowl of radius .R. If the coefficient of friction is then the insect can only crawl upto a height of
detailed solution
Correct option is A
See fig.The insect will crawl up the bowl till the component of its weight down the plane just equals the force of limiting frictionF=Wsinα and N=Wcosαμ=tanα=F/N=1/3 But tanπ2−α=cot α=xR2−x2 so that X=3/10=0⋅949RNow h=R−x=0⋅051R.Talk to our academic expert!
