A square metal plate with a hole is at temperature `theta` is present on smooth horizontal surface. Point `P & C` are marked on the plate, where C is centre of mass of the plate with the hole shown. When temperature of the plate is increased then the point.

A

P-shifts towards left

B

P shifts towards right

C

C shifts towards left

D

C shifts towards right

Text Solution
