Physics Question from JEE Main 2023 · 1 February, Shift 1

An object moves with speed v1,v2,v3v_1, v_2, v_3 along the line segments AB, BC and CD respectively, where A, B, C and D are four points marked in that order on one straight line. Where AB = BC and AD = 3AB, then the average speed of the object will be:

  • A

    (v1+v2+v3)3\frac{(v_1 + v_2 + v_3)}{3}

  • B

    v1v2v33(v1v2+v2v3+v3v1)\frac{v_1 v_2 v_3}{3(v_1 v_2 + v_2 v_3 + v_3 v_1)}

  • C

    3v1v2v3v1v2+v2v3+v3v1\frac{3v_1 v_2 v_3}{v_1 v_2 + v_2 v_3 + v_3 v_1}

  • D

    (v1+v2+v3)3v1v2v3\frac{(v_1 + v_2 + v_3)}{3v_1 v_2 v_3}
