A cube of side a is placed on an inclined plane of inclination `theta`. What is the maximum value of `theta` for which the cube will not topple?

A

`15^@`

B

`30^@`

C

`45^@`

D

`60^@`

Text Solution

Verified by Experts

The correct Answer is:
C
The cube will not topple until the line of action of `CM` passes through the cube.

That is `tantheta=(AX)/(OX)=(a/2)/(a/2)` or `theta=45^@`
