A horizontal board is performing simple harmonic oscillations horizontally with an amplitude 0.3 m and a period of 4 s . The minimum coefficient of friction between a heavy body placed on the board if the body is not to slip is.

Options

  1. A=0.05
  2. B=0.075
  3. C=0.173
  4. D=1.14

Correct answer

B. =0.075

Step-by-step solution

The maximum acceleration of oscillation, aligned & a_ = ^2 A g= ( 2 T )^2 A & = 4 ^2 0.3 (4)^2 10 =0.075 aligned
