The force constant of two springs are  K1\;{K_1} and K2{K_2} Both are stretched till their elastic energies are equal. If the stretching forces are F1{F_1} and F2,{F_2}, then F1:F2{F_1}:{F_2} is
View answer and explanation
Correct option: C
K1:K2\sqrt {{K_1}} :\sqrt {{K_2}}
Option C (K1:K2\sqrt {{K_1}} :\sqrt {{K_2}}) is correct because it is derived from equating the elastic potential energies and relating them to the stretching forces.
