A block of mass Mis pulled vertically upwards

through a rope of mass m by applying force Fon

one end of the rope. What force does the rope

exert on the block?

$\huge{\fcolorbox{black}{grey}{\large{\fcolorbox{white}{black}{{\fcolorbox{grey}{purple}{❤AnSwEr❤}}}}}}$

let T be the tension in the string.

for mass M-

T= Ma

Also considering mass m + M as system-

F =(M+m)a

therefore -

a= F/(M+m)

substituting-

T= FM/(M+m).

this is the force which rope exerts on block.
