Two, spring P and (Q) of force constants...

Two, spring P and _(Q) of force constants `K_(p)` and `k_(Q)(k_(Q)=(kp)/2)`are stretched by applying forces of equal magnitude. If the energy stored in` _(Q) ia E,` then the energy stored in P is

A

2

B

2E

C

E/8

D

E/4

Text Solution

Verified by Experts

The correct Answer is:
B

`E_(p ) =(1)/(2 ) K_(p)x^(2)`
` E_(Q ) =(1)/(2) K_(Q ) x^(2)`
`(E_(p ))/(E _(Q))=(K_(p))/(K_(Q ))=2implies E_(p) = 2E_(Q ) = 2E `
