Question

Identical springs of steel and copper are equally stretched.On which more work will have to be done?

Answer 1

Answer:

Explanation:

Steel because steel have more density than copper

Answer 2

More work will have to be done on the steel wire because uska youngs modulous jayada hota hai copper wire se.

Youngs modulous is directly proportional to elastic potential energy

by the formula

U = 1 Y*(strain)^2 * volume

2

And steel alloy hai and usually iski density bhi copper se jayada hoti hai

to obviously usko stretch krne mein jayada work krna padega.

Khushi here✔️✌
