Question

11
ske
A block of mass 8kg is kept on smooth horizontal surface as
shown. Draw the FBD of the block. Find its acceleration and the
force exerted by the block on the floor.
12
mi
Two blocks of masses mı = 10 kg and m2 = 5 kg are in contact on a
frictionless table. A horizontal force of F = 15N is acting on mass
m2 find the force of contact between mi and m2

bord hadies, the group of bodies which are having same acceleration (t​

Answer 1

Answer:

Let the tension be T and acceleration be a. Then,

From  FBD of block of mass 8Kg  

T=8a               ..... eq.1

And, From  FBD of block of mass 2Kg  

2g−T=2a

⇒T=20−2a=8a                  

⇒a=2m/s  

⇒T=8a=16N
