Question

There are two mass less spring A and B of spring constant KA  and KB respectively KA>KB . If WA and WB be denoted as work done on A andwork done on B respectively, then



Correct Answer
A

if they are compressed to same distance,

Correct Answer
B

if they are compressed by same force (upto equilibrium state) 

Your Answer
C

if they are compressed by same distance,

Your Answer
D

if they are compressed by same force (upto equilibrium state)


Solution

The correct options are
A

if they are compressed to same distance,


B

if they are compressed by same force (upto equilibrium state) 


WA=12KAx2;WB=12KBx2 KA>KBWA>WB

If the springs are compressed by same force

F=KAxA=KBxB;xA=FKA;xB=FKB;

WAWB =12KAF2K2A12KBF2K2B=KBKA

WA<WB
