A body A of mass 1 kg rests on a smooth surface. Another body B of mass 0.2 kg is placed over A as shown. The coefficient of static friction between A and B is 0.15 . B will begin to slide on A , if A is pulled with a force greater than

Options

  1. A1.764 N
  2. B0.1764 N
  3. C0.3 N
  4. DIt will not slide for any F

Correct answer

A. 1.764 N
