Answer:

The force is 274 N.

Step-by-step explanation:

In figure 2:

(d) Let the tension in the string is T.

According to the Newton's second law,

Net force = mass x acceleration

Apply for 200N.


T - 200 sin 35 =(200)/(9.8)* a \\T - 114.7 = 20.4 a..... (1)\\220 - T = (220)/(9.8)* a\\220 - T = 22.45 a..... (2)\\Adding both the equations\\334.7 = 42.85 aa =7.81 m/s^(2)

Now put in (1)

T - 114.7 = 20.4 x 7.81

T = 274 N
