A dynamometer D is attached to two bodies of masses M=6 kg and m=4 kg.

1.	A dynamometer D is attached to two bodies of masses M=6 kg and m=4 kg. Force F=20 N and f=10N are applied to the masses as shown. The dynometer reads
Answer» 10N 20N 6 N 14 N Solution :(d) Acceleration of system, `a=(F-f)/(M+m)=(20-10)/(6+4)=1 ms^(-2)"" ` (TOWARDS left) Let `F_(0)` be the reading of DYNAMOMETER, then equation of motion of MASS m would be, `implies F_(0)=f+ma=10+(4)(1)=14N`
