Question

Two bodies whose masses are m = 50 kg and
m2 = 150 kg are tied by a light string and are placed
on a frictionless horizontal surface. When m is pulled
by a force F, and acceleration of 5 ms is produced
in both the bodies. Calculate the value of F. What is
the tension in the string ? (Ans. 1000 N, 750 N)
-2​

Answer 1

Answer:

750 meter per second square

Answer 2

Answer:

ANSWER

Taking both bodies together as a system-

F=(m

1

+m

)a

⟹F=200×5=1000N

Now, consider only m

2

The only force moving it is tension.

So, T=m

2

a

⟹T=150×5=750N
