Question

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

Answer 1

Answer:

The value of T2 is 9 N

Explanation:

Three blocks A, B and C weighing 1, 8 and 27 kg respectively are connected.

Then the total mass will be: 1+8+27= 36 kg

T3 is equal to 36 N.

As blocks are connected  with each other hence the acceleration of the blocks = 36/36= 1 m/s ^2

T3 is equal to 36 N.

Now the force applied on block A, F1= m1a1= 1x1 = 1 N

force applied on block A, F2- F1= m2a2= 8 x 1= 8 N

F2- F1 = 8 N

putting value of F1

F2= 9 N
