  2. But Sir doesn’t the mass move vertically up also along with the horizontal motion. As the net upward force on the block by the spring should be -kx = 2000x.02= 40N whereas the downward force is only 1g i.e. 9.8N so it should be moving vertically too by 1.5 cm to reach vertical equilibrium. So doesn’t that affect the solution Sir?

  6. sir why we talk about potential energy in this example as potential is only been talk about in conservative field force ?

    Ans 1 ->
    spring force resulting from an ideal spring is a conservative force.

    Ans 2 ->
    in the final state the restoring force is perpendicular to motion of block so why isnt the work done by the spring in the final state o
