Tension in the rope at the rigid support is (g=10 m / s 2)

Question

Tension in the rope at the rigid support is (g=10 m / s 2) (A) 760 N (B) 1360 N (C) 1580 N (D) 1620 N

For 40 kg 400-T1=40(1) T1=360 N for 50 kg 500+T1-T2=50(2) ⇒ T2=760 N for 60 kg ⇒ T3-600-T2=60 (2) T3=1580 N T3 will be the tension at the topmost point on the rigid support.

Q. Tension in the rope at the rigid support is $(g = 10 m / s^{2})$

760 N

1360 N

1580 N

1620 N

For $40 k g$
$400 - T_{1} = 40 (1)$
$T_{1} = 360 N$
for $50 k g$
$500 + T_{1} - T_{2} = 50 (2)$
$\Rightarrow T_{2} = 760 N$
for $60 k g \Rightarrow T_{3} - 600 - T_{2} = 60$ (2)
$T_{3} = 1580 N$
$T_{3}$ will be the tension at the topmost point on the rigid support.
