Amazing.

[@alishamureed7906]

Isn't the extension same in parallel? So why is x half for B?

[@cursedstone7939]

Same question

[@mariameltourkey8628]

extension is divided on both springs so it will decrease to the half.

[@chickunt3nders]

extension must be same as the force applied for it to be K in parallel 0.5F/0.5 X will give us f/x which is K

[@BOBO_4869]

In Professor Lewin's video about elasticity, he had a really good explanation: to maintain in equilibrium, each spring has to exert a spring force that counteracts the tensile force applied. So that way the net force is zero, hence in parallel the forces on springs are shared

the correct answer is (A )miss pls correct it :)

Wait how?
