Two identical spring constant K are attached to a block of mass m and to fixed supports as shown in Fig. When the mass is displaced from equilibrium position by a distance x towards right, find the restoring force. |
Answer» Forces on the spring are F1 = −kx (left spring) F2 = −kx (right spring). Restoring Force, F = F1 + F2 = −2kx ∴ F = −2kx towards left |
