Two metal plates P and Q of same material are arranged as shown in the figure. If both the plates are uniformly heated through the same range of temperature, then

A

both x and y increase

B

both x and y decrease

C

x decreases and y increase

D

x increases and y decrease

Text Solution

Verified by Experts

The correct Answer is:
B
According to the question, both the plates P and Q uniformly heated through the same range of temperature, So, both the plates expands outward . Therefore, both the distance x and y decreases.
