Two identical wires of substances 'P' and 'Q' are subjected to equal stretching force along the length. If the elongation of 'Q' is more than that of 'P', then

A

both P and Q are equally elastic

B

P is more elastic than Q

C

P is plastic and Q is elastic

D

Q is more elastic than P

Text Solution

Verified by Experts

The correct Answer is:
B
Elasticity is the ability of a body to resist a distorting influcence. Since, in this question it is given that 'Q ' is more elongated than that of P so, P has more resisting strength than Q, i.e., P is more elastic than Q. Hence, the option (b) is correct.
