Question

10. Two masses of 10 kg and 5 kg are suspended
from a rigid support as shown in figure, The
system is pulled down with a foree of 150 N
attached to the lower mass. The string
attached to the support breaks and the system
accelerates downwards.
10 kg
5 kg
ISON
In case the force continues to act.what will be
the tension acting between the two masses?
1) 300 N 2) 200 N 3) 100 N
4) zero​

Answer 1

Given,

Two masses 10kg,5kg,

Force=150N

So the acceleration of the system is a=

m

)g

=

10+5

150+(10+5)×10

=

15

300

=20 m/s
