This question has statement `1` and statement `2` . Of the four choice given after the Statement , choose the one that best describe the two Statement .
If the spring `S_(1) `and `S_(2)` of force constant `k_(1)` and `k_(2)` respectively , are streached by the same force , it is found that more work is done on spring `S_(1)` then on spring `S_(2)`
Statement -1: If statement by the same answer work done on `S_(1)` work on `S_(1)` is more then `S_(2)`
Statement - 2 : `k_(1) ltk_(2)`

A

If both assertion and reason are corret and reason is a correct explanation of the assertion .

B

If both assertion and reason are correct but reason is ot the correct explanation of assertion .

C

If assertion is correct but reason is incorrect .

D

If both assertion and reason are incorrect .

Text Solution

Verified by Experts

The correct Answer is:
A
`F = k_(1)x_(1) =k_(2)x_(2)`
Work done on the spring is stored in the potential energy
`U 1/2 kx^(2) = (F^(2))/(2k)`
As per the second statement ,`k_(1)lt k_(2)`
So `W_(1) gt W_(2)`
