A square is made of four rods of same material one of the diagonal of a square is at temperature difference `100^@C`, then the temperature difference of second diagonal:

`0^(@)C`

`100/(l)`

`100/(2l)`

`100^(@)C`

Text Solution

Verified by Experts

The correct Answer is:

Square is made of four rod of same material, so that temperature difference of second diagonal will be zero due to symmetry.
