If `k_(s)` and `k_(p)` respectively are effective spring constant in series and parallel combination of springs as shown in figure, find `(k_(s))/(k_(p))`. A. `(9)/(2)`B. `(3)/(7)`C. `(2)/(9)`D. `(7)/(3)` |

Answer» Correct Answer - C The effective spring constant `k_(s)` of this arrangement is `(1)/(k_(s))=(1)/(k)+(1)/(2k)rArr(1)/(2k_(s))=(2+1)/(2k)=(3)/(2k)` `." "k_(s)=(2k)/(3)` The effective spring costant `k_(p)` of this arrangement is `k_(p)=k_(1)+k_(2)=k+2k=3k` `therefore" "(k_(s))/(k_(p))=(2k//3)/(3k)=(2)/(9)` |
