What will happen to the springy iron strip if the current stops

Using the information given in the question, we have no way to tell.

Is it an air current ?  Is it a water current ?  Is it an electric current ?

Are the springy iron strip and the current related somehow ?

Are they even on the same planet ? ?

it would be kevlar ^^

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
