Two blocks of masses \( 6 \mathrm{~kg} \) and \( 4 \mathrm{~kg} \) connected by a rope of mass \( 2 \mathrm{~kg} \) are resting on a frictionless floor as shown in the following figure. If a constant force of \( 60 \mathrm{~N} \) is applied to \( 6 \mathrm{~kg} \) block, then the tension in the rope at points \( \mathrm{A}, \mathrm{B} \) and \( \mathrm{C} \) are respectively given by:
(1) \( 60 \mathrm{~N}, 60 \mathrm{~N}, 60 \mathrm{~N} \)
(2) \( 30 \mathrm{~N}, 25 \mathrm{~N}, 20 \mathrm{~N} \)
(3) \( 20 \mathrm{~N}, 25 \mathrm{~N}, 30 \mathrm{~N} \)
(4) \( 20 \mathrm{~N}, 20 \mathrm{~N}, 20 \mathrm{~N} \)
\( \mathrm{P} \)
