If the coefficient of friction between an insect and bowl is `mu` and the radius of the bowl is r, find the maximum height to which the insect can crawl in the bowl.

A

`(r)/(sqrt(1 + mu^(2)))`

B

`r[1- (1)/(sqrt(1+ mu^(2)))]`

C

`rsqrt(1 + mu^(2))`

D

`r[sqrt(1 + mu^(2))- 1]`

Text Solution

Verified by Experts

The correct Answer is:
