Apparent Weight & Lift

A block of mass M placed inside a box descends vertically with acceleration 'a'. The block exerts a force equal to one-fourth of its weight on the floor of the box. The value of 'a' will be

Show answer and solution

Answer: (c)

  1. Box descends with aa: N=M(g−a)N = M(g - a).
  2. M(g−a)=Mg4⇒a=3g4M(g - a) = \frac{Mg}{4} \Rightarrow a = \frac{3g}{4}
  3. So the answer is (c) 3g4\frac{3g}{4}.
