Two spring of spring constant k(1) and k...

Two spring of spring constant `k_(1)` and `k_(2)` are joined in series The effective spring constant of the combination is given by

A

`sqrt(k_(1)k_(2))`

B

`(k_(1)+k_(2))//2`

C

`k_(1)+k_(2)`

D

`k_(1)k_(2)//(k_(1)+k_(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
`k_(eq)=(k_(1)k_(2))/(k_(1)+k_(2))` as `[(1)/(k_(eq))=(1)/(k_(1))+(1)/(k_2)]`.
