In the figure the minimum value of `a` at which the cylinder starts rising up the inclined surface is

A

`g tan theta`

B

`g cot theta`

C

`g sin theta`

D

`g cos theta`

Text Solution

Verified by Experts

The correct Answer is:
A
On the cylinder
If `N =` normal reation between ylinder and inclinder plane
`N sin theta =` horizontal component of `N`
`= ma` …(i) `N cos theta =` vertical component of `N`
`= mg` …(ii)
Driving eq.(i) by (ii) we get,
`tan theta = (a)/(g)`
`a = g tan theta`
