A bimetallic strip consists of metals $A$ and $B$ . It is mounted rigidly at the base as shown. The metal $A$ has a higher coefficient of expansion to that for metal $B$ . When bimetallic strip is placed in a cold bath it will

A

bend towards the right

B

bend towards the left

C

not bend but shrink

D

neither bend nor shrink

Solution
