two bodies whose masses are m1 = 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)

Answer:
m1=50
m2=150
a=5m/s
F=ma
F= 150+50=200
F= 200*5=1000N
