A push of magnitude p acts on a box of weight w as shown in the figure. the push is directed at an angle θ below the horizontal, and the box remains a rest. the box rests on a horizontal surface that has some friction with the box.

A solenoidal inductor for a printed circuit board is being redesigned. To save weight, the number of turns is reduced by one-fifth, with the geometric dimensions kept the same.
