A spring has a natural length of \( 50 \mathrm{~cm} \) and a force constant of \( 2.0 \times 10^{3} \mathrm{Nm}^{-1} \). A body of mass \( 10 \mathrm{~kg} \) is suspended from it and the spring is stretched. If the body is pulled down to a length of \( 58 \mathrm{~cm} \) and released, it executes simple harmonic motion. What is the net force on the body when it is at its lowermost position of its oscillation? (Take, \( g=10 \mathrm{~ms}^{-2} \) ).
P
(a) \( 20 \mathrm{~N} \)
(b) \( 40 \mathrm{~N} \)
(c) \( 60 \mathrm{~N} \)
(d) \( 80 \mathrm{~N} \)
