Question

If two bodies of masses 4 kg and 6 kg are connected by a string such that both

are in vertical plane. If g = 10 m/s2

then​

Answer 1

Answer:

Since 6kg is heavier than 4 kg so it will accelerate down while 4 kg will accelerate up

So the equation of net force on 6kg is given as

6×10−T=6a

 equation of net force on 4kg is given as

T−4×10=4a

now add the above two equations

6×10−(4×10)=(6+4)×a

60  - 40 = 10a

a = 2m/s2

So 6 kg will accelerate downwards while 4 kg will accelerate upwards 

with acceleration 2 m/s2

now in order to find the tension force

T−4×10=4×2

T = 48N

So the tension in the string is 48 N
