A double inclined plane as shown in the figure has fixed horizontal base and smooth faces with the same angle of inclination of 30^ . A block of mass 300 ~g is on one face and is connected by a cord passing over a frictionless pulley to a second block of mass 200 ~g kept on another face. The acceleration with which the system of the blocks moves is ........ % of acceleration due to gravity.

Options

  1. A5
  2. B10
  3. C15
  4. D20

Correct answer

B. 10

Step-by-step solution

From free body diagram Adding Eqs (i) and (ii), we get aligned & (m₂-m₁ ) g = (m₁+m₂ ) a & a= (300-200) g 30^ (300+200) & a= 1 10 g & a=10 % of g & aligned
