Two springs with different spring constants, k₁ and k₂, are connected as shown in the figure below. A force F is applied to one end. The force exerted by the wall on the spring is (take + to the right) A) 0 B) -k₁ $\Delta$x₁ C) -k₂ $\Delta$x₂ D) F E) -F

Question

Quizplus · Accepted Answer

Since the force is being applied towards the left, the spring will compress and push back towards the right, with a force opposite in direction to the applied force. Therefore, the force exerted by the wall on the spring will also be towards the right, opposite in direction to the force exerted by the spring on the wall. Hence, the answer is -F.

Two Springs with Different Spring Constants, K1 and K2, Are Δ\DeltaΔ

Two Springs with Different Spring Constants, K₁ and K₂, Are $\Delta$
