Value of `theta` is increased gradually from `theta = 0`. At `theta = tan^(-1) (1/2)` both the blocks just start slipping. Than value of `mu_2` is : (`g= 10m//s^2`)

A

0.5

B

0.4

C

0.6

D

0.3

Text Solution

Verified by Experts

The correct Answer is:
C
At limiting case (10+20) g `sin theta=[(10)(0.3) +20 mu_(2)] g cos thetarArr mu_(2) =0.6`
