Two concave mirrors of equal radii of curvature R are fixed on a stand facing opposite directions. The whole system has a mass m and is kept on a frictionless horizontal table as shown in the figure. Two blocks A and B , each of mass m , are placed on the two sides of the stand. At t = 0 , the separation between A and the mirrors is 2R and also the separation between B and the mirrors is 2R . The block B moves toward

Options

  1. A(a) x = - 2R 3 , R (b) x = -2R, 0 (c) x = -3R, 4R 3
  2. B(a) x = - R 3 , 2R (b) x = -R, 0 (c) x = -2R, 5R 3
  3. C(a) x = - 3R 2 , R (b) x = -2R, 0 (c) x = -3R, 5R 3
  4. D(a) x = - 2R 3 , R (b) x = -R, 0 (c) x = -2R, 4R 3

Correct answer

A. (a) x = - 2R 3 , R (b) x = -2R, 0 (c) x = -3R, 4R 3

Step-by-step solution

(a) x = - 2R 3 , R (b) x = -2R, 0 (c) x = -3R, 4R 3
