Question

Q A body of mass m 1 equal to 20 kg is placed on a smooth
horizontal table This body is connected to a string which passes
over a frictionless pulley The string also carries another body of
mass m 2 equal to 10 kg at the other end
Find out the acceleration which will be produced when the nail
fixed on the table is removed also find out the tension in the
string during the motion of the bodies What when the bodies stop
Take g = 10 N/kg

Dear Student,
When bodies start moving  let tension in the string is T and acceleration is a so a=Net pulling force Total mass=10×g20+10=13gand by free body diagram of mass m210×g-T=10×g/3T=10×g-10×g/3=20g/3=200/3 Nand when bodies are in rest then Tension =10g=10×10=100N
