Question

two bodies of masses 2 kg and 4 kg are connected to the ends of a string of negligible mass and then passed around a frictionless Pulley. Calculate 1. acceleration of the system 2. tension in the string and take g equals to 10 m/s^2

Answer 1

Hope the solution helps

Answer 2

Let tension be T and acceleration be a m1=2 kg and m2=4 kg
So, T-m1g=m1a............(i)
m2g-T=m2g.............(ii)
Solving eq. simultaneously we get
m2g-m1g=m1a+m2a
Putting value of m1 and m2
a=20/6
Putting value of T in eq 1
We get T= 80/3
