Question

Three blocks A, B and Cweighing 1, 8 and 27 kg respectively are connected as shown in the figure with an inextensible string and are moving on a smooth surface. Tz is equal to 36 N. Then T2 is C B 1. A TA Tz T3 (a) 18 N (b) 9M (d) 1.25 N (c) 3.375 N​

Answer 1

Answer:

T3=36N

Considering all the three blocks in a system-

Fext=maT3=36a36=36a⇒a=1m/s2

Next,

Considering only box C in a sytem

Fext=maT3−T2=27a36−T2=27

(1)⇒T2=36−27=9N
