A

1. unable to change by itself the state of rest

B

2. unable to change by itself the state of uniform motion.

C

3. unable to change by itself the direction of motion.

D

4. unable to change by itself the state of rest or of uniform motion

Name the property of an object by virtue of which it opposes or tends to oppose any change in its state.

The property of a body by virtue of which it tends to regain its original configuration as soon as the deforming forces applied on the body are removed is called elasticity. Coefficient of elasticity, E = (stress)/("strain") = (F//a)/(Delta l//l) = (F l)/(pi r^2(Delta l)) The value of E depends upon nature of material. A material with higher value of E is said to be more elastic. Read the above passage and answer the following question : (i) Which is more elastic steel or rubber ? Why ?
