Man A of mass 2m is standing on a ladder of mass m. Ladder is attached with an inextensible light string and man C of mass 3m is holding the other end of string. Initially the whole system is at rest. Assume whole system is at sufficient height and pulley is ideal. Also A and C are at same horizontal level. Then choose the CORRECT option(s):

Options:(select one or more)

Answer:
A, C
Solution:

Equations: , , .

(A) with C at rest w.r.t. the rope (): solving gives m/s, so m/s and m - correct.

(B) with A at rest w.r.t. the ladder: solving gives , so and , not 2 m - wrong.

(C, D) : and substitution gives m/s upward - (C) correct, (D) wrong.
