A brass disc fits snugly in a hole in a steel plate. Shou,d you heat or cool tyhe system to losen the disc from the hole ? given that `alpha _b gt alpha _Fe`.

Text Solution

Verified by Experts

The correct Answer is:
C
(##DCP_V03_C20_E01_009_S01##).
Since, `alpha_ B gt alpha_(Fe)`
On cooling brass will contract more.
