Physics Question from JEE Main 2026 · 23 January, Shift 2

A bead P is sliding on a frictionless semi-circular string (ACB) and it is at point S at t=0t = 0, and at this instant the horizontal component of its velocity is vv. Another bead Q of the same mass as P is ejected from point A at t=0t = 0 along the horizontal string AB, with the speed vv. Friction between the beads and the respective strings may be neglected in both cases. Let tPt_P and tQt_Q be the respective times taken by beads P and Q to reach the point B. Then the relation between tPt_P and tQt_Q is:

A horizontal string AB drawn as the straight chord from A on the left to B on the right, with the semi-circular string ACB bulging below it through the point C. Bead Q sits at A on the horizontal string with a short arrow pointing right along AB; bead P sits at the point S on the lower arc, and the dashed line drawn from near A to a point on AB marks an angle of 45 degrees with AB.
  • A

    tP>tQt_P > t_Q

  • B

    tP>1.25tQt_P > 1.25 t_Q

  • C

    tP=tQt_P = t_Q

  • D

    tP<tQt_P < t_Q
