A uniform rectangular block has length twice as large as the breath. It is lying on the horizontal plane, which is gradually being raised so as to be inclined to the horizontal at an angle `theta`. For what value `theta`, the block be at the point of toppling?

A

`70.6^(@)`

B

`65.8^(@)`

C

`45.5^(@)`

D

`26.6^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
The block will be at the verge of toppling if the vertical line from the centre of mass just passes from within its base

`therefore tantheta=((a)/(2))/(a)=0.5impliestheta=26.6^(@)`
