Three identical rigid circular cylinder ...

Three identical rigid circular cylinder `A` `B` and `C` are arrenged on smooth inclined surfaces as shown in figure. The laest value of theta that prevent the arrangement from collapes is.

Text Solution

Verified by Experts

The correct Answer is:
C
Three identical smooth cylinders (rigid) are arranged as shown. The least value of `theta` that prevent the arrangement from collapse is `tan_(-1).(1)/(sqrt(3))` then find the value of integer x :
