A 2 ~kg brick begins to slide over a surface which is inclined at an angle of 45^ with respect to horizontal axis. The co-efficient of static friction between their surfaces is:

Options

  1. A1.7
  2. B1 3
  3. C0.5
  4. D1

Correct answer

D. 1

Step-by-step solution

aligned & mg 45= f _ L & mg 45= N & f _ L = _ s N & _ s = 45=1 aligned or = _s ( is angle of repose) 45= _ s =1
