Question

4 blocks of masses m, 5 kg, 8 kg and
m2 are arranged on smooth horizontal
surface. A force of 52 N accelerates all
blocks with 2 m/s2. The ratio of m, to m2
is 3:10. Find the value of tensions T1, T2
and T3 which are shown below.
​

Answer 1

Answer:

ANSWER

Let a be the acceleration of the system.

T1=M1a .....(1)

T2−T1=M2a ....(2)

F−T2=M3a ......(3)

Adding (1), (2) and (3)  we get

 (M1+M2+M3)a=F

or  (10+20+30)a=60⇒a=1m/s2

Now , T2=(M1+M2)a=(10+20)(1)=30N
