Answer 1

Given two blocks of masses M and m, And

Given two blocks of masses M and m, Anda force F acting on the block of mass M pulling it outside

Given two blocks of masses M and m, Anda force F acting on the block of mass M pulling it outsideThe two masses system can be considered as a whole, With F

Given two blocks of masses M and m, Anda force F acting on the block of mass M pulling it outsideThe two masses system can be considered as a whole, With F being the only external force acting on them.

Given two blocks of masses M and m, Anda force F acting on the block of mass M pulling it outsideThe two masses system can be considered as a whole, With F being the only external force acting on them.Here the spring force has been ignored as while considering the two system as a whole, it will be accounted as an internal force for the system

Now both the masses are moving with this same acceleration towards the direction of force

Now both the masses are moving with this same acceleration towards the direction of forceAcceleration of mass m = a (as the system is moving as a whole)

Now both the masses are moving with this same acceleration towards the direction of forceAcceleration of mass m = a (as the system is moving as a whole)Force on the mass m= mass times acceleration

Now both the masses are moving with this same acceleration towards the direction of forceAcceleration of mass m = a (as the system is moving as a whole)Force on the mass m= mass times acceleration Force = ma
